Samarium Cobalt Magnet

SmCo magnet permanent magnet material is a type of rare earth permanent magnet. The permanent magnet is made of the rare earth elements samarium, cobalt and other elements. It has high magnetic energy product and extremely low temperature coefficient, and the maximum operating temperature can reach 350°C.

Compared with NdFeB, samarium cobalt permanent magnets are more suitable for working in high temperature environments. They can still maintain good temperature stability and chemical stability above 180°C, and they have strong corrosion resistance and oxidation resistance. .

SmCo magnets are widely used in aerospace, defense industry, microwave devices, communications, medical equipment, various magnetic transmission devices, sensors, magnetic processors, motors, magnetic cranes, etc.
