Introduction of rare earth permanent magnet powder
Rare earth permanent magnet material is a kind of magnetic material which is made of alloys composed of samarium, neodymium mixed rare earth metals and transition metals (such as cobalt, iron, etc.), pressed and sintered by powder metallurgy method, and magnetized by magnetic field. Rare earth permanent magnets are divided into samarium cobalt (SmCo) permanent magnets and neodymium iron boron (NdFeB) permanent magnets. The magnetic energy product of SmCo magnets is between 15 and 30 MGOe, and the magnetic energy product of NdFeB permanent magnets is between 27 and 50 MGOe. Known as "permanent magnet king", it is the highest magnetic permanent magnet material at present.
