As a part of the rare earth magnet family, samarium cobalt (SmCo) magnet is a strong permanent magnet with special magnetism. They have excellent temperature stability and anti-demagnetization ability. This is one advantage over rare earth neodymium magnets. Maximum operating temperatures of rare earth samarium cobalt magnets is between 250 and 350 °C; Curie temperatures range from 700 to 800 °C. SmCo magnets are very suitable for applications involving high or very low temperature. In these applications, high magnetic strength is required, magnetic stability is very important, space is a limiting factor.

Samarium cobalt(SmCo) magnets not only have the feature of high-temperature resistance, they also have excellent corrosion resistance,which is another advantage over neodymium rare earth magnets. So surface coating treatment is unnecessary for most samarium cobalt rare earth magnets application. However, the surface of samarium cobalt magnets used in some special environments can also be electroplated. Nickel plating is the most common surface treatment for SmCo magnets.

Rare earth samarium cobalt (SmCo) magnets have excellent temperature stability and can maintain their magnetism under extreme temperature conditions. Therefore, they are very suitable for technical applications requiring high performance and magnetic strength in very high or low temperature environment. Our samarium cobalt magnets are used in semiconductor, wind energy, electric power, petroleum ,energy,automotive, aerospace, medical, military and industrial manufacturing,
