Samarium cobalt performance

Samarium cobalt magnet introduction and performance table

Introduction: Samarium cobalt magnets are the second generation of rare earth permanent magnets, mainly divided into 1:5 type (SmCo5) and 2:17 type (Sm2Co17). Its main features are high magnetic performance and good temperature performance. The working temperature can reach 250-350 degrees Celsius. Compared with neodymium iron boron magnets, samarium cobalt magnets are more suitable for working in high temperature environments. It is very suitable for manufacturing various high-performance permanent magnet motors and application products with very complicated working environment. In addition, samarium cobalt magnets are extremely resistant to corrosion, and their surface generally does not require electroplating. Samarium, the main component of samarium cobalt magnets, has low reserves on the earth, so its price is very expensive.
