Ferrite is an oldest magnet material and also is most widely used at present.
It also called black magnet. Its maximum magnetic energy is low, but its excellent temperature proof,
steady property, cheap price determine its wide usage in speakers, motors, sensors, medical devices.
Sintered NdFeB Magnet
Sintered NdFeB is a most general permanent magnet of rare earth, which processes high maximum magnetic
energy and high intrinsic coercive force. It is widely used in motor, speakers, magnetic separator,
magnetic therapeutics and other high-tech fields.
