Block NdFeB permanent Magnet
NdFeB magnet(Neodymium magnet) is made from Neodymium, Iron, Boron and some other transitive metallic elements to make it strong.
1. General features of the NdFeB magnet:
- Grade: N33, N35, N38, N40, N42, N48, N50, N52 (M, H, SH, EH, UH)
- Coating: Ni, Ni-Cu-Ni, Zn, Ag, Au and other special platings and coatings
- Shape: arc, tile, square, cylinder and magnetic ring with various sizes
- High magnetic performance (Br: 11,000 to 14,500 GS, Hcj: 11,000 to 30,000 Oe, BHmax: 35 to 50 MGOe)
- Maximum working temperature: 80 to 200 centigrades
- Super strong magnetic force and high intrinsic coercive force and also with precise tolerance
2. Application: Sensors, motors, rotors, wind turbines, wind generators, loudspeakers, magnetic hooks, magnetic holder, filters automobiles and so on;
