In permanent magnetic materials, the highest performance of sintered Nd-Fe-B magnets, commercial products the maximum magnetic energy product (BH) max=360kJ/m3, but lower the Curie temperature of the magnet (314 DEG C), temperature stability and corrosion resistance is poor, and limit the use under high temperature and in most cases need by coating protection. The manufacturing technology of the neodymium iron boron magnet has the powder metallurgy method and the melt quick quench method. Due to excellent magnetic properties, Nd-Fe-B type magnets have been widely used. It is mainly used in electric motors, generators, acoustic transducers, sensors, medical devices and magnetic machines.
