01. Introduction to Samarium Cobalt Magnets

Samarium cobalt magnet is also a rare earth magnet, which is a permanent magnet made of Samarium, Cobalt, and other metal materials in a ratio. Its main characteristics are high magnetic properties and good temperature resistance. Samarium cobalt magnets have a high magnetic energy product and high coercivity, making them more suitable for working in high-temperature environments compared to neodymium iron boron. Samarium cobalt has excellent corrosion resistance, so generally no coating is required.

However, due to the special molecular structure of samarium cobalt, it is relatively fragile and fragile. In addition, the main component of samarium cobalt, samarium, has low reserves on Earth, making it very expensive. Samarium cobalt can be divided into two categories based on its composition: SmCo5 and Sm2Co17, which are first and second generation rare earth permanent magnet materials, respectively.
