Samarium Cobalt Magnetic Material

Rare earth permanent magnet material is a kind of magnetic material which is composed of samarium and neodymium mixed rare earth metal and transition metal (such as cobalt, iron, etc.), sintered by powder metallurgy and magnetized by magnetic field. Rare earth permanent magnets are divided into samarium cobalt (SmCo) permanent magnets and NdFeB (NdFeB) permanent magnets. Among them, the magnetic energy product of SmCo magnets is between 15--30MGOe, and the magnetic energy product of NdFeB magnets is between 27--50MGOe, which is known as the "permanent magnet king" and is the highest magnetic permanent magnet material.
