Rare earth sintered NdFeB magnet
Product Description
Rare earth sintered NdFeB magnet
NdFeB(Neodymium Iron Boron)magnet is an alloy magnet made from Nd, Fe, B and other metal elements. As the third generation of rare earth permanent magnets, it is by far the best performance in contemporary.
Features:
1. high performance, cost ratio
2. high intrinsic coercive force after concocting
3. it can stand high working temperature, up to 200℃
4. it is prone to corrosion in humid environments, need surface treatment: Zinc, Nickel, Silver, Gold-plating, Phosphor, rubber and Spray Epoxy Resin.
5. quick delivery and good service
6. it is easily formed into various sizes
Production process:
