Sintered NdFeB Magnet
Neodymium magnet, also well known as NdFeB magnet, is the strongest permanent magnet material in the world. Neodymium Magnet is one member of rare earth permanent magnets, neodymium rare-earth magnet, another common rare earth magnet is the SmCo magnet.
Compared with other permanent magnet materials, sintered neodymium magnet has outstanding advantages in magnetic properties. It has extremely high magnetic energy product, coercivity, and energy density, at the same time, its mechanical properties are easy to process. These excellent properties have made sintered NdFeB permanent magnets widely used in modern industry and electronic technology. The common ones are permanent magnet motors, speakers, magnetic separators, computer disk drives, and magnetic resonance imaging equipment. In 2000, the output value of rare earth permanent magnets surpassed ferrite for the first time. In 2010, the output value of sintered neodymium permanent magnet surpassed ferrite, becoming a veritable “protagonist” in the permanent magnet industry.
