(2) Development status of global and Chinese single crystal materials After more than 40 years of development, China's synthetic diamond industry has made great progress from scratch, from small to large, from technology to scale, and synthetic diamonds and various products not only It meets the development requirements of various fields of the national economy and exports to all parts of the world, making outstanding contributions to the development of the national economy. At the beginning of the birth of synthetic diamond, its application was greatly limited due to its high production cost. After more than 40 years of development, with the mature production technology and production technology of synthetic diamond, the production cost of synthetic diamond has dropped drastically, the demand for synthetic diamond in various fields has been increasing, and the artificial diamond industry in China has also developed rapidly. Due to the many excellent properties of synthetic diamonds, as the grade of synthetic diamonds continues to increase, the range of applications will become more and more extensive, and will continue to maintain a relatively high growth rate in the expected longer period. According to industry association data analysis, the market demand for synthetic diamond in China in the next few years can still maintain an average annual compound growth of more than 15%.
(3) The application of synthetic diamond in emerging industries is expected to further expand. With the continuous improvement of synthetic diamond grade, its excellent performance is expected to be more widely used in high-tech fields, such as aerospace instrument bearings, radar waveguides, Processing of precision instruments such as optical components and high-energy smokers; it can be used for cutting, grinding, satellite solar panels, etc. of single crystal silicon and polycrystalline silicon 0.1-0.2mm thick sheets; it can be used for large-scale integrated circuits such as computer chips. Fine precision cutting, slotting, backside thinning, nano-diamond polishing, etc.; high-purity large single crystal diamond can also be used to produce high-strength optical windows for dynamic compression testing, window openings for some devices in very environmental environments, and research cores. Components of fusion energy and so on.
The developed countries in the world all regard superhard materials and products including synthetic diamonds as the development focus. The research and application level of superhard materials and products represent the level of scientific and technological development of a country to some extent.
2. Polycrystalline materials (1) Overview of polycrystalline materials and their main products In 1977, GE successfully developed PCD and PCBN, marking the beginning of a new phase of human application of superhard materials. With the development of polycrystalline material technology, its material properties are continuously improved, and the scope of application is also expanding to many fields of industrial processing and production. At present, polycrystalline materials are mainly used for manufacturing cutting teeth of geological mineral drilling tools, mold blanks of high-grade drawing die and various industrial tool cutting heads, and the corresponding intermediate products of polycrystalline materials mainly include oil/natural gas drill bits. High-end drilling grade composite sheets such as PCD composite sheets (hereinafter referred to as “petroleum composite sheetsâ€), medium and low-end drilling grade composite sheets such as PCD composite sheets for coalfield/mine tools (hereinafter referred to as “mine composite sheetsâ€), and PCD high grades Drawing blanks (hereinafter referred to as "PCD drawing blanks") and PCD/PCBN tooling composite sheets (hereinafter referred to as "tool composite sheets").
1 Petroleum composite sheet Petroleum composite sheet is made by ultra-high pressure high-temperature synthesis process (combination pressure is generally around 6.5GPa, synthesis temperature is generally above 1,450 degrees Celsius) and refined post-treatment process (such as spark discharge treatment and surface etching treatment) Etc.) Made of high-end drilling grade composite sheets. The petroleum composite sheet has high strength, hardness, wear resistance, impact resistance and good self-sharpness. These excellent properties make it suitable for use in the petroleum and natural gas exploration and mining industries. The petroleum composite sheet can be processed to meet the specific requirements according to the drilling formation and the drilling machine, and is fixed as a cutting tooth of the oil/natural gas drill bit on the drill bit, and is a core component for manufacturing the above-mentioned drill bit. The original petroleum composite sheet is mainly used for the manufacture of drill bits for core or full drilling in soft to medium hard formations and moderately compressive medium compressive strength formations, in high compressive strength, densely cemented abrasive sandstone, vermiculite It is not working well with granite. However, in recent years, with the improvement of the quality of petroleum composite sheets and the improvement of drill bit design and manufacturing level, its application in hard interlayer and hard formation drilling has made a major breakthrough. China has introduced drill bits made of petroleum composite sheets since the early 1980s, and has been widely promoted and applied in major oil fields in China. In addition to its application in oil/gas mining, the petroleum composite sheet production process can also be used to manufacture other high-end drilling grade composite sheets such as tapered composite sheets, which are used in coal mining, mining and road repair. Specific segmentation areas.
2 Mining composite sheets Mining composite sheets are low-end drilling grade composite sheets made by high-pressure high-temperature synthesis process (combination pressure is generally not more than 6GPa, synthesis temperature is generally not more than 1,450 degrees Celsius). Compared with high-end drilling-grade composite sheets such as petroleum composite sheets, the performance requirements of PCD composite sheets used in coal mining/mine mining operations are slightly lower. This is mainly due to the fact that except for certain areas, coalfield mines and other general operating strata are shallow, and the geological conditions are not as harsh as the geological conditions of oil and natural gas mining operations. The service life and wear resistance requirements of drill bits are relatively low, and downstream customers The price of the drill bit is more sensitive. In addition to the industrial field, the application of composite sheets for mining has gradually penetrated into various fields of national life. For example, in the field of urban construction, welding composite sheets for mines to piling bits and wind cannon bits can greatly improve construction efficiency; In the transportation sector, mine composite sheets can be used to make core drills for piers.
3 PCD drawing die blank Drawing die is a very important consumable mold for drawing wire rods of various metal wire manufacturers (such as wire and cable factory, steel wire factory, welding wire welding factory, etc.). The wire drawing die has a wide range of applications, and is mainly used for drawing straight, difficult-to-machine objects such as bars, wires, wires, pipes, etc., and is suitable for drawing and processing of metal and alloy materials such as steel, copper, tungsten, and molybdenum. Since the cost of the drawing die accounts for more than 1/2 of the drawing cost, reducing the cost of the drawing die and increasing its service life are urgent problems that the metal wire production unit needs to solve (source: China CNC Machine Tool Network). PCD drawing die blank is the main material for producing high-grade wire drawing die. PCD wire drawing die is used for drawing copper, aluminum, stainless steel and various alloy wires. Its service life is 100-300 times that of hard alloy wire drawing die, and it is pulled. The wire has a uniform size, high finish and high output.
4 Composite sheets for cutters are mainly used for the production of superhard tools for non-ferrous metals and alloys and non-metallic materials other than iron-based metals. Since the chemical composition of PCD is carbon, high temperatures are required when cutting ferrous metals such as iron. In the case of chemical reactions, which affect the production effect and service life, the superhard tools for the production of ferrous materials mainly use PCBN tool composite sheets. The super-hard tool made of the composite sheet with the tool not only has better hardness and wear resistance than the traditional cemented carbide tool, but also can achieve better surface finish of the workpiece during hard cutting, and realize the grinding by the car.
(2) Development status of global and Chinese polycrystalline materials Currently, global high-end polycrystalline materials are mainly produced by enterprises in the United States and Japan, and most of the mid-to-high-end market share is from DI, ES, US Synthetic, Sumitomo, and Korea. It is controlled by leading international large group companies. China's superhard materials and products industry has achieved rapid development since the 1970s, and has become the world's largest manufacturing country of superhard materials, but the proportion of single crystal materials is large, and the production scale of polycrystalline materials is small. The high-end polycrystalline material market has been controlled by foreign companies, such as high-grade composite blades for large-sized tools, composite sheets for petroleum used in hard formations, etc., and Chinese enterprises have significant gaps in production and quality with well-known foreign companies. Most products need to be imported.
(3) Analysis of market capacity and supply and demand of polycrystalline materials Due to the wide application in the downstream field and the large consumption in use, polycrystalline materials have huge market capacity; on the other hand, they are a new type of material with superior performance. The substitution effect of polycrystalline materials on traditional materials is obvious, so polycrystalline materials have broad potential market space.
1 Drilling grade composite drilling grade composite sheet products can be divided into high-end drilling grade composite sheets (such as petroleum composite sheets and tapered composite sheets) and low-end drilling grade composite sheets (such as mining composite sheets) according to different production processes. Wait). Drilling grade composite sheet products are widely used in a wide range of applications, and there are a large number of cross-applications (such as oil composite sheets can be applied to specific sub-fields where coal drilling/mining requires high drilling efficiency, and mining composite sheets can also be used. Used in oil exploration operations with good geological conditions), so the following is only the analysis of the two representative market applications of drilling grade composites:
a. Oil exploitation market The demand for composite sheets in the oil exploitation market is mainly determined by the market demand for downstream oil drill bits, and the demand for oil drill bits is mainly determined by the oil market demand and oil production enterprise oil production plan. Although the international oil price was significantly reduced in 2008 due to the economic crisis, the strong dependence on the oil supply in the world economic development has not changed substantially. Therefore, the demand for oil and petroleum drill bits will remain strong in the coming decades. According to the “General Plan for High-tech Industrial Chains with Regional Characteristics of Superhard Materials and Products in Henan Provinceâ€, the consumption of petroleum geological drill bits in China reached 3 billion yuan in 2006, assuming a logical calculation based on the amount of oil geological drills consumed by oil production and consumption, 2009 In the year, China's petroleum geological bit consumption was about 3.095 billion yuan (affected by the financial crisis, China's crude oil output in 2009 only increased by 3.17% compared with 2006, data source: National Bureau of Statistics). 30%-40% of the production cost of petroleum geological drill bit is the raw material cost (data source: Guoxin Securities Jiang Diamond Shares In-depth Report), which is composed of composite sheets according to the production cost of 30% of petroleum geological drill bits, excluding the industrial gross profit margin of 38% of the drill industry. Calculation (according to the integer value of the arithmetic mean of the gross profit margin of the drill series products from 2007 to 2009), the demand for composite sheets in China's oil exploration market in 2009 was about 576 million yuan. Considering that the increase in the demand for composite sheets is closely related to the growth of the drill industry, according to the growth rate of the drill industry in the next three years (take the growth forecast data of 2010 diamonds from 2010 to 2012, Wind Information), by 2012, China Petroleum The demand for composite sheets in the mining market will reach 822 million yuan. According to the year-end statistics of global oil production and oil and gas reserves released by the US Oil and Gas Journal on December 21, 2009 and the National Bureau of Statistics of China, China’s oil production in 2009 accounted for only 5.36% of global oil production, with oil production and consumption. The scale of the petroleum drill bit is proportional to the logical calculation. In 2009, the global oil drill bit market was about 57.7 billion yuan, and the composite film market capacity was 10.7 billion yuan. The market development space is huge.
b. Mining market In 2009, China's raw coal output was 2.965 billion tons, up 343 million tons year-on-year, up 13.08% year-on-year; in the first quarter of 2010, China's raw coal production was 750 million tons, up 148 million tons year on year, up 24.58% year-on-year (data) Source: Wind information). As the world's largest coal producer, China's coal mining industry has a huge market capacity. According to the Coal Industry Association, during the 11th Five-Year Plan period, only the newly-built coal mine investment-derived equipment business opportunities amounted to 77 billion yuan. If equipment upgrades and mechanization rates are considered, the overall equipment business opportunity will be nearly 100 billion yuan (source: KGI Securities Shanhe The intelligent research report), the resulting demand for composite film is also quite amazing. Mineral resources are non-renewable resources and an important material for the country's strategic reserves and industrial development. In recent years, China has set off a new round of prospecting boom, so the workload of drilling and prospecting is very large, and the demand for mining drills will also increase sharply. According to market research by Financial Mail Innovation, composite drill bits will replace the various types of drills made by traditional tungsten compound Tungsten carbide. The latter's market capacity in 2006 has reached 15 billion US dollars, calculated according to the annual growth of 5%, 2009 composite film The existing and potential market capacity of the drill bit has reached US$17.4 billion, or approximately RMB110-120 billion. According to the composite film accounting for 30% of the cost of the drill bit and 38% of the industrial gross profit margin of the drill industry, after deducting the global oil exploration market demand for composite sheets of about 10.7 billion yuan, the global demand for composite sheets in the mining market has reached 98. 100 million yuan.
2 PCD drawing die blank drawing die market is driven by the huge demand for wire rod in industrial production and engineering construction, and the market capacity is considerable. However, due to the high production cost and high price of PCD drawing die blank, only some of the drawing effect is currently End users with higher precision requirements use PCD drawing die blanks, so their market capacity is relatively limited. According to the “General Plan for High-tech Industrial Chain of Regional Super-hard Materials and Products of Henan Province†and the relevant departments of industry associations, the global market capacity of PCD drawing die blanks in 2010 will exceed RMB 1.2 billion.
3 Tool composite sheet According to the “General plan for high-tech industrial chain of regional super-hard materials and products in Henan Provinceâ€, China's PCD/PCBN tool market will reach 4 billion yuan in 2010 and reach 9 billion yuan in 2012. In 2010, China's tool composite sheet market will reach 960 million yuan, and will reach 2.16 billion yuan in 2012.
(4) Prospects for the development of polycrystalline materials 1 Prospects for the development of polycrystalline materials are more optimistic Polycrystalline materials are the newest composite materials with the highest hardness to date, and have higher hardness, better wear resistance and thermal conductivity than traditional materials such as cemented carbide. The advantages of higher performance and better processing performance are widely used in traditional fields such as machinery, metallurgy, geology, petroleum, coal, stone, wood, construction, automobile, home appliances, etc., high-tech fields such as electronic information, aerospace, and defense. With the development of modern technology, products with higher strength and hardness appear in industrial production and daily life, and there must be harder and stronger materials to process these products. Therefore, the development prospect of polycrystalline materials is more optimistic.
a. Material characteristics are outstanding, and the production process is mature. Polycrystalline materials are novel materials that are characterized by extremely remarkable industrial production and processing. They have unique functions and hardness, and are difficult to be replaced by other materials. In addition, the production process and process of polycrystalline materials have been relatively mature. The development of China's technology and equipment level has the ability to manufacture related polycrystalline material products, and large-scale production of polycrystalline materials to meet the needs of downstream industrial enterprises. Necessity and practical feasibility.
b. The downstream demand is strong and the market space is quite impressive. The government's current strategy for economic development focuses on optimizing the industrial structure, improving efficiency, reducing consumption, and protecting the environment. Scientific, comprehensive, coordinated and sustainable development, GDP 2020 The year will be quadrupled from 2000, and the national economy is developing rapidly. The implementation of projects such as the lunar landing, large aircraft manufacturing, the West-East Gas Transmission, the South-to-North Water Diversion, urbanization construction, and the 4 trillion investment plan to promote economic growth also indicates that China's macroeconomic and manufacturing development space is still huge. From the development of the user industry, during the “Eleventh Five-Year Plan†period, China's crude oil output will enter a period of steady growth. In 2009, China's oil production has reached 189 million tons (China Petroleum Futures Network); real estate construction area from 2005 to 2009 Almost doubled, the output of marble granite slabs almost doubled from 2005 to 2009. The output of metal cutting machine tools increased by 64.71% from 2005 to 2009, and the output of automobiles, engines and bearings increased by 1.41 and 2.51 respectively. 1.79 times. The rapid and steady growth of the polycrystalline material terminal products market will bring greater development opportunities and broad market space for the production of polycrystalline materials.
c. It has obvious advantages in replacing traditional superhard alloy materials, and has broad prospects for future development. Polycrystalline materials are the newest composite materials with the highest hardness so far. Compared with traditional materials such as hard alloys, they have higher hardness, better wear resistance and thermal conductivity. The advantages of higher performance and better processing performance make it superior in terms of service life, processing quality and processing efficiency, and greatly exceed traditional hard alloy materials. At the same time, polycrystalline materials, as an alternative to hard alloys, also have the advantages of abundant raw materials, energy conservation, and industrial upgrading of the processing industry. For example, each wire drawing die diamond polycrystalline material can save an average of 100 cemented carbide molds. The cemented carbide is made of strategic resources cobalt (Co), tungsten (W) metal, and the polycrystalline material is obtained by ordinary graphite conversion, polycrystalline The application of materials can save the country a lot of strategic resources such as tungsten and cobalt; the friction coefficient of PCD drawing die is only one-third of that of traditional hard alloy materials. Under other conditions, PCD drawing die can save more than 60% of energy; The use of crystal materials enables the original hard alloy to be processed, and the processing efficiency is high, the processing quality is good, and the long life of the polycrystalline material reduces the number of replacement of processing tools, thereby greatly promoting the machining and drilling industry. Industrial upgrading. Therefore, although polycrystalline materials are more expensive than traditional superhard alloy materials, with the further reduction of the price of polycrystalline materials and the recognition of the performance of polycrystalline materials by downstream customers, the future development space and potential market capacity of polycrystalline materials are Very huge.
2 China needs to focus on developing high-end products in the field of polycrystalline materials. The internal material accumulation and external market demand for the development of polycrystalline materials in China are relatively mature. China has become the world's largest producer of superhard materials. The raw materials required for the production of polycrystalline materials, such as diamond, alloy, molybdenum cup and zirconium cup, are abundantly supplied. The national industrial policy strongly supports and the skilled labor supply is abundant. At the same time, the national The economy and manufacturing industry have a strong desire to upgrade the industrial structure in the process of rapid development. The substitution effect of polycrystalline materials on traditional cemented carbide materials has been in machinery, metallurgy, geology, petroleum, coal, stone, wood, construction, electronics. Information, aerospace, defense, military, automotive, home appliances and other more and more areas are reflected, market demand is strong. Technology research and development is the only bottleneck restricting the industry to develop high-end polycrystalline material products market. In order to get rid of the current low-quality and low-price competition of domestic polycrystalline material manufacturers, only through research and development to break through the high-tech polycrystalline material technical barriers, to quality products and international It is the correct choice for domestic manufacturers to conduct all-round competition.
3. Superhard material terminal products (1) Overview of superhard material terminal products Superhard material terminal products are mainly divided into two categories: single crystal material terminal products and polycrystalline material terminal products. The end products of single crystal materials mainly include abrasive tools and sawing tools; and the end products of polycrystalline materials mainly include cutters, drilling tools and drawing die.
1 Single-crystal material terminal products Diamond grinding tools are referred to as abrasive tools. The specific products include diamond grinding blocks, grinding wheels and grinding discs. Diamond grinding tools are mainly used for rough polishing, grinding and polishing of various stone, wall and building floor surfaces. Diamond sawing tools are widely used. The specific products include stone cutting saw blades, optical glass cutting saw blades, handicraft cutting saw blades, and refractory cutting saw blades.

The specific products of drilling tools mainly include oil drill bits, geological and mining drill bits.
(2) Development status, market capacity and development prospects of super-hard materials terminal products Super-hard materials end products and super-hard materials are the upstream and downstream relationship of the industrial chain, and the two influence each other and are closely related. This report has explained the development status, market capacity and development prospects of super-hard materials in the analysis of super-hard materials. It will not be described here. For details, please refer to “II. The industry in which the company is located. "The basic situation of the "(4) Superhard materials and products sub-sector industry status and development prospects" "1, single crystal materials" "(3) analysis of market capacity and supply and demand of single crystal materials" and "2 "(3) Analysis of market capacity and supply and demand of polycrystalline materials".
4. Excipients for processing superhard materials (1) Excipients for processing superhard materials and their main products Overview Excipients for processing superhard materials belong to the category of metal powders in a broad sense. Metal powder refers to elemental (or alloy) powdery metal solid particles having a specific particle size, shape and physicochemical properties prepared by physical or chemical methods. Metal powder can be widely used in powder metallurgy products, spray materials, coatings, catalysts, etc. Applications include aerospace, machinery, chemicals, automobiles, motorcycles, electronics, agricultural machinery, superhard materials and other industries. The metal powder for superhard material products is mainly used for preparing a sintered body of a super-hard material, and the abrasive grains of the super-hard material are fixedly held to form an effective cutting, grinding and drilling unit body (or composite). Metal powder for superhard material products can be divided into two types: elemental powder and prealloyed powder. The elemental powder refers to a powdery solid particle having a single metal component prepared by physical or chemical means. The prealloyed powder refers to a powder solid particle having two or more metal component components prepared by physical or chemical methods. At present, there is no national classification standard for pre-alloyed powder. According to the actual application, it is generally divided into basic pre-alloyed powder and professional pre-alloyed powder. The basic prealloyed powder has a relatively simple composition, generally a binary or ternary alloy powder, and has strong versatility, and can be widely used as a base sintering component in various sintered products of superhard materials. Professional pre-alloyed powder refers to alloy powder with a cost-effective combination of ternary and above. It is highly targeted and only suitable for certain types of super-hard materials.
(2) Development of metal powder for superhard material products The gap between production equipment and control technology determines the quality of metal powder products for superhard material products at home and abroad, which leads to the sintering of superhard material products in China. Mainly used in the mixing and sintering of elemental metal powder. Although leading enterprises such as the Yellow River Cyclone have continued to promote the application of pre-alloyed powders in recent years and achieved good results, the metal powders used in the production of high-end super-hard materials in China still rely mainly on imports, and the annual consumption is in the hundreds of millions.
(3) Analysis of market capacity and supply and demand of metal powder for super-hard materials products 1 International market with the production of super-hard materials gradually shifted to developing countries such as China, the consumption of metal powder for super-hard materials in developed countries showed a downward trend . In 2009, the consumption of metal powder for superhard materials in developed countries was about 10,000 tons, of which the consumption of elemental powder accounted for about 40% (mainly carbonyl iron powder, cobalt, nickel, copper, tin), prealloyed powder. Consumption accounts for about 60% (mainly chemically prepared iron-cobalt/nickel-copper prealloyed powder and copper-tin alloy powder).
2 Domestic market Since metal powder is generally used in combination with super-hard materials, there is a close relationship between the consumption of metal powder and the consumption of super-hard materials. According to the statistics of the Superhard Materials Industry Association, the current ratio of metal bond tools to total superhard material products is about 85% (data source: Proceedings of the 5th Zhengzhou International Superhard Materials and Products Symposium), according to each The formula for the production of metal-like binders is estimated to be 1:49 for superhard materials and metal powders. In 2009, the output of synthetic diamonds in China was about 5.4 billion carats (equivalent to 1,080 tons). In proportion, in 2009, the consumption of metal powder for superhard material products in China was over 44,000 tons. Due to the relatively lagging production technology of pre-alloyed powder and the slow expansion of production capacity, domestic super-hard material products enterprises mainly use single-mass powder for production. The consumption of elemental powder accounts for more than 90% of the consumption of metal powder for all super-hard materials. The domestic market has just started to use pre-alloyed powder. Before 2007, the annual consumption of various types of pre-alloyed powders (basic pre-alloyed powders and professional pre-alloyed powders) was less than 1,000 tons. In the past three years, the market consumption has been greatly increased. The growth trend, the consumption of pre-alloyed powder in the domestic market in 2009 has exceeded 3,000 tons.
(4) Development prospects of metal powder for super-hard material products The key to the performance of super-hard material products is the holding force of the metal powder sintered body on the super-hard abrasive grains and the wear adaptability between the sintered body and the abrasive grains. The performance of the sintered metal powder body mainly depends on the degree of alloying when the metal powder particles interact. Due to the coarseness of the elemental powder and the poor uniformity of dispersion, the alloying in the sintering process is only at the interface of the metal powder particles, and the degree of alloying is very limited, resulting in poor comprehensive mechanical properties of the powder sintered body, and superhard abrasive grains. The ability to hold and the wear resistance with superabrasive grains is poor, which limits the performance of superhard products. The pre-alloyed powder is a pre-dispersed combination of the required multi-component components to achieve uniform mixing at the atomic level to form a uniform aggregate of multi-component components, and the prepared alloy particles are fully alloyed internally, and the degree of alloying of the sintered body is High, uniform and stable performance, the holding power of super-hard abrasive grains is also greatly improved; at the same time, the pre-alloyed powder has better wear adaptability with super-hard abrasive grains, which can greatly improve the comprehensive performance of super-hard material products. The application of prealloyed powder is an effective way to improve superhard material products, and is an inevitable trend in the development of superhard materials and products. According to the statistics of the Superhard Materials Industry Association, the average annual compound growth rate of China's synthetic diamond production will exceed 15% in the next three years (data source: China Superhard Materials Technology Development Forum Proceedings), calculated according to this ratio, China's super hard in 2012 The consumption of metal powder for materials and products can reach 68,431 tons, and the market has a broad space for growth. Prediction of consumption of synthetic diamond and metal powder: (Unit: ton) 2010 2011 2012 Artificial diamond 1,2421,4281,643
Metal powder for superhard material products 51,72959,47668,431
With the localization of pre-alloyed powder production, the downstream super-hard material products enterprises will gradually improve their understanding of pre-alloyed powders, and domestic similar products have price advantages compared with imported products. It can be expected that the domestic pre-alloyed powder market capacity will be further expanded. Consumption forecast of elemental powder and prealloyed powder Unit: ton 2010/2011/2012 Total consumption of metal powder for superhard materials products 51,72959,47668,431
Elemental powder accounts for 80%, 60%, 35%
Elemental powder consumption 41,38335,68623,951
Pre-alloyed powder accounts for 20%, 40%, 65%
Pre-alloy powder consumption 10,34623,79044,480
1. Single crystal material (1) Single crystal material and its main products Overview Single crystal materials (including synthetic diamond and cubic boron nitride) have excellent properties such as high hardness, good wear resistance and thermal conductivity, and low thermal expansion coefficient. Machining, stone processing, geological drilling, electronics, construction, aerospace, new materials processing, automotive and other fields. As the most important single crystal material, synthetic diamond has broad application prospects, and Western developed countries even regard it as a strategic resource. The synthetic equipment and process of synthetic diamond is an important indicator to measure the level of a country's basic industry. In recent years, with the gradual recovery of the world economy, the economic growth of the world's major industrial countries has increased significantly, and the demand for industrial diamonds has gradually increased.
