NdFeB magnet is divided into sintered NdFeB and bonded NdFeB. Bonded NdfeB magnet is magnetic in all directions and corrosion-resistant. And sintered NdFeB magnet is easy corrosion, the surface needs coating. The sintered NdFeB is generally divided into axial and radial magnetization according to the required working face. Sintered NdFeB permanent magnet material has excellent magnetic properties, widely used in electronics, electric machinery, medical instruments, toys, packaging, hardware machinery, aerospace and other fields, the more common permanent magnet motor, loudspeaker, magnetic separator, computer disk drive, magnetic resonance imaging equipment and meters.
