Detailed information

Sintered neodymium-iron-boron (NdFeB) permanent-magnet material’s major composition of NdFeB magnets is Nd2Fe14B, it is the highest magnetism performance permanent-magnet material at present, that can be made into the complex shape magnet, and cut.

Property:

The (BH) max value of the sintered NdFeB magnet is about 5 to 15 times higher than sintered ferrite magnets. Hcj value is 5 to 10 times higher than sintered ferrite and 6 to 10 times higher than AINiCo magnets.
The potential magnetic properties of NdFeB magnets are very high. Theoretically, their (BH) Max value can be as high as 527 KJ/m3(66MGOe). They can even attract object which weight is 640 times higher than themselves.


Application field:

The sintered NdFeB magnets earliest mainly application was for the high performance motor: voice coil motors (VCM’s) in hard disk drives, brushless DC motors.
Other applications include magnetic separation, magnetic resonance imaging, sensors and loudspeakers etc
