Sintered NdFeB magnets with its excellent performance

One, Sintered NdFeB magnetss which applications?

Sintered NdFeB magnets with its excellent performance, abundant raw material and reasonable prices are to the rapid development and wide application. The main applications in micro motors, permanent magnet instrument, electronic industry, automobile industry, petrochemicals, nuclear magnetic resonance devices, sensors, audio equipment, magnetic suspension system, magnetic transmission machine and magnetic devices and so on.

Second, by those who NdFeB material composition?

Sintered NdFeB magnetss main raw materials are rare earth neodymium (Nd) 32%, metals iron (Fe) 64% non-metallic elements and boron (B) 1% (small amount of dysprosium (Dy), terbium (Tb), cobalt (Co), niobium (Nb), gallium (Ga), aluminum (Al), copper (Cu) and other elements). NdFeB permanent magnet materials based on Nd2Fe14B ternary compound as the substrate, and its composition should be similar formula with a compound Nd2Fe14B. But exactly Nd2Fe14B composition ratio, the magnets are very low, or even non-magnetic. A magnet which is the actual content ratio of neodymium and boron compound Nd2Fe14B neodymium and boron content is large in order to obtain better magnetic properties.
