Sintered NdFeB Magnet Composition and Microstructure

Sintered NdFeB Magnet Composition Sintered NdFeB magnet contains three essential elements: rare earth neodymium, iron and boron. Nd atoms, coupling with ferromagnetic Fe atoms, help the magnet obtain high remanence Br and maximum energy product (BH)max, which makes it extraordinary compared with other permanent magnets. Although B element has only around 1 wt% in the magnet, it is necessary for the intermetallic phase stability, so the magnet has stable magnetic properties. In commercial sintered NdFeB magnet, Nd element is usually… Read More
