What is Samarium Cobalt Magnet?
Samarium cobalt magnets or samarium magnets is one kind of rare earth magnets made from Samarium, Cobalt, Iron, Zirconium etc which was developed in the early 1970s. There are first generation rare earth magnets-SmCo5 magnets and second generation rare earth magnets-Sm2Co17 magnets base on different compositions.The half finihsed products of Samarium cobalt magnets are made from raw materials by powder metallurgy technology, including melting ,casting, crashing, milling, pressing ,sintering, then they are made into finished products by machining process, such as cutting, wire cutting, grinding, even coating. Mag Spring's factory can supply highest grade Sm2Co17 magnets in the world with the following magnetic properteris: Br – 1,15 T, Hcj - 2300 kA / m, Hcb - 820 kA / m, BH (max) – 250 kJ/m3.
Samarium magnets are feature of higher working temperature ratings, higher coercivity and excellent corrosion resistant. They usually do not need coating to protect them from environment-induced corrosion because of contenting high percentage of cobalt metals which allows more accurate tolerances and simplifies use. Also they can work for long time in high temp more than 250-350 Centigrade degree and can work more stable than Neodymium magnets.
Samarium cobalt magnets are commonly used in high performance motors, magnetic couplings, magnetic separators, sensor controls, oil pump and other equipments which performance is required to be consistent with temperature change or under easy corrosion circumstance.
Mag Spring is a professional supplier of high quality Samarium cobalt magnets ( Samarium Magnets) from China .We can supply Samarium Permanent Magnets with highest properties in China because our factory base on one famous magnetic materials institude since 1967.
