Compared with other permanent magnet materials, sintered NdFeB magnets boast outstanding magnetic properties, featuring ultra-high maximum energy product, coercivity, and remanence.
They also exhibit excellent mechanical properties and are readily machinable to precise dimensions.
These exceptional characteristics make sintered NdFeB permanent magnets widely applied in modern industry and electronic technologies.
Typical applications include permanent magnet motors, loudspeakers, magnetic separators, computer disk drives, magnetic resonance imaging (MRI) equipment, and more.
