Neodymium magnet is mainly made of Neodymium, Iron and Boron. Neodymium magnet is offered in range of operation tem 80ºC to 220ºC. A sintered Neo magnet has high remanence, high coercive force, and is easily formed into various sizes and shapes. The magnet is suitable for being used in DC Motor, Brushless motor , Speaker, MRI  and others.

II. Features :Â
Since NdFeB magnets easily corrode, it is often coated to protect against this. Traditional coatings are Nickel, Zinc, and Epoxy with other options available. Selection of a coating should be discussed early on in the design and application process. Sintered  NdFeb canbe made in Arc, cylinder,ring and some irregular shape.
