NdFeB Magnets

Performance

Sintered NdFeB

Neodymium Iron Boron(Nd-Fe-B), the most powerful Rare Earth magnets available today, possesses high energy ranging from 8 MGOe to 64MGOe and wonderful coercive force. As the third generation of Rare Earth permanent magnet, NdFeB products are less brittle than SmCo, Nd-Fe-B magnet is widely used in motor, instrument, aviation and the hightech field.
