About Sintered NdFeB : Sintered Neodymium-iron-boron ( NdFeB ) , known as the third generation of rare earth permanent magnet, is made from 32% of Nd, 64% of Fe, 1% of B (Nd 12 Fe 14 B) as well as few of other elements like Dy, Tb, Co, Nb, Ga, Al, Cu, etc.

Its Characteristic:

• known as “king of magnet” for its high Br( remanence ), high coercive force, and high BH(max energy). Its BH can be more than 400KJ/M 3 . Due to its strong coercive force and (BH)max, it can suck heavy objects weighing 600 times its weight. Compared with ferrite magnet of same volume, Its (BH)max is ten times as high as ferrite magnets. So to get the same magnetic fields, we can replace big ferrite magnet with small NdFeb.

• Steady property. Stocked in suitable temperature, moisture, etc without interfered magnetic fields, the magnetic property can be almost lasting forever.

• But hard and crisp. During operation, the operator should be very careful in case the magnets impact each other to threaten the safety and break themselves into pieces.

• But easy to be erosive.

Its application:

mainly applied in VCM of computer disk drive, Magnetic resonance imaging(MRI), acoustic equipment, microwave communication, magnetic machines( magnetic pump, magnetic valve), home appliance, etc. With the improvement of magnetic property, NdFeB has been used in other new high-tech fields.
