nian tian magnet is the third generation of rare earth permanent magnet NdFeB strong magnet is the strongest performance of the permanent magnet in the magnet. The value of BHmax ferrite magnet 5-12 times, is the AlNiCo magnets 3-10 times; its coercive force equivalent to 5-10 times the ferrite magnets, AlNiCo magnets 5-15 times, its potential magnetic properties can suck up high, equivalent to 640 times its own weight.

As the main raw material of neodymium iron boron magnet iron is very cheap, rare earth neodymium samarium storage quantity is 10-16 times more, the price is low a lot of samarium cobalt magnet.

Neodymium iron boron magnet mechanical properties than samarium-cobalt magnets and AlNiCo magnets are good, easy cutting and drilling and complex shape processing.

Neodymium iron boron magnet is the inadequacy of its poor performance under high temperature, the use of magnetic loss is bigger, the highest working temperature is low. Generally 80 degrees Celsius, after special treatment of the magnet, the highest working temperature can reach 200 degrees celsius.

Because the material contains a lot of neodymium and iron, it is easy to rust is also a major weakness. So the neodymium iron boron magnet must surface coating. May electroless nickel ( Ni ), zinc ( Zn ), gold ( Au ), chromium ( Cr ), epoxy resin ( Epoxy ) etc..

Neodymium iron boron magnet is widely used in aerospace, electronics, electrical, instrumentation, medical and other fields. And the technology has become more and more widely used, such as adsorption magnet, toys, jewelry and other.
