  • Neodymiu Magnet are mainly composed of neodymium(32%), iron(64%), boron(1%), and a few quantity rare earth material, such as Dy, Tb, Co, Nb, Ga, Al, Cu,etc. Neodymium magnet is regarded as “Magnet King” due to its recorded high remanence, coercive force and maximum energy product.
  • With Neodymium magnet rapid development, many high-tech products were developed. Especially its application in motors makes products miniaturization and micromation. At the same time, because of its high remanence, coercive force and maximum energy product, this type magnet is widely used in servo motor, flat brushless motor, step motor, IT products, Nuclear Magnetic Resonance, speaker and other products.
  • Neodymium magnet is easily rust and oxidated, so their surface must be plated Zn, Ni, Silver, Gold or made phosphor and epoxy treatment.

★ Application of NdFeB magnet

 

The NdFeB permanent magnet is a kind of energy material, which can produce the stable magnetic field in the certain space. Because of its highest coercive force and , especially under the 20℃~150℃, it works better than any other kinds of permanent magnets. So it is widely used in many areas, especially in the high-tech area. Basing on its physical principle, the usual applications are as below:

Electric energy to mechanical energy: as electromotor,speaker,VCM (Voice Coil Motor);

Mechanical energy to electric energy: like the generators, telephone receiver, and measuring instrument;

Mechanical energy to Mechanical energy: as the magnetic separator, magnetic suspension, magnetic actuators and magnet chucks;

Magnetic field’s physical effect: like the Nuclear magnetic resonance, magnetic cleaning device and magnetic oil-saving mechanism.
