Samarium cobalt magnet is a rare earth magnet. It is a kind of magnet made of samarium, cobalt and other rare earth metal materials. Samarium cobalt magnet was developed in 1970. Samarium cobalt magnet is a strong magnetic magnet with high magnetic energy product (BHmax), high coercivity, fragility and easy cracking. The large magnetic energy products of samarium cobalt magnets range from 9 MGOe to 31 MGOe. Samarium cobalt magnets have two composition ratios: (samarium: cobalt)1:5 and 2:17. For example, the 2:17 alloy has a large magnetic energy product of 26 MGOe, a coercivity of 9750 Oersted, a Curie temperature of 825°C and a high operating temperature of 350°C.
