Samarium Cobalt Magnet is one main type of four kinds of rare earth permanent magnet , i.e. SmCo, consist of samarium, cobalt and other rare earth metal elements. They are made after smelting, grinding, molding and sintering of these raw materials.

SmCo magnets own high magnetic energy and low temperature coefficient. Their highest working temperature is 250℃ to 350 ℃ and no limitation of negative temperature. In operating temperature above 200 ℃, the maximum magnetic energy product, temperature stability and chemical stability of samarium cobalt magnets  are even better than that of neodymium permanent magnets.
 
Moreover, Samarium Cobalt Magnets have strong oxidation resistance and corrosion resistance. Therefore, they are extensively used in fields of national defense, aerospace, microwave devices, communication, medical equipments, and instruments, all kinds of magnetic transmission devices, sensors, magnetic processors, high temperature motors, and magnetic crane and so on.
 
China Rare Earth Magnet Limited manufactures both SmCo5 and Sm2Co17 magnets as per clients/ users' demands. BH Curves and testing report of SmCo magnets can be provided after we completing the production of each order.

The main magnetic properties like Br., HcB, HcJ and BH(Max) will be learned from the BH Curve of SmCo permanent magnet material.
