5.High density (up to 65% denser than Lead). 
Denser materials exist (pure Tungsten, Gold, platinum group metals) but their use is restricted by availability, workability and cost. 
Providing mass where volume space is limited. 
Concentrated weight essential where accuracy is required in placement of mass. 
Placement of weight in situations where airflow has a significant impact.
 

6.Thermal Properties

High softening temperature. 
Low thermal conductivity and low coefficient of expansion gives the material a high resistance to thermal fatigue.
Excellent soldering erosion resistance to molten aluminium. Strong at high temperatures with high thermal stability.

7.Mechanical Properties 
High Young's modulus of elasticity. Does not creep when experiencing significant forces, unlike Lead. 
Despite their strength, they remain ductile and resistant to cracking. 
The hardness range of the alloys is typically 20-35 Hardness HRC. 

8.Standard and safe Packing
1)paper wrapped the sheets, then plastic paper protected from moisture
2)Foam board around the the inner wooden case
3)Standard exported plywood case outside

9.Delivery time:
 10-35days as your required qty.

10.The advantage of us
1) leading producer, more than 20 years producing experience
2) factory direct sales, low price in the market
3) the whole production line from powder to finished products, top and steady quality assured
4)fast delivery and best after-sale service
