Introduction of Samarium Cobalt (SmCo) magnets
SmCo magnet is a type of magnetic material made from rare earth metal samarium and strategic metal cobalt-main elements, with iron, copper, zirconium and praseodymium, and produced by a serial of process melting, milling, pressing, sintering and aging. It has high magnetic properties (high energy product, high coercivity, high remanence), very low-temperature coefficient (-0.030% / °C), high working temperature (Maximum working temperature reaches 350°C), no negative temperature limitation, and excellent corrosion resistance. At working temperature above180°C, its maximum energy product, temperature stability and chemical stability are better than NdFeB material.
More information for Samarium Cobalt (SmCo) magnets
According to the different components of the SmCo5 and Sm2Co17, respectively, they are the first generation and the two generations rare earth permanent magnetic material. Because of its raw materials are scarce, the price is expensive and limit the development. Samarium cobalt (SmCo) as the second generation rare earth permanent magnet, not only has a high magnetic energy product (14-28MGOe) and reliable coercivity and exhibits excellent temperature characteristics in rare earth permanent magnet series. Compared with the NdFeB, SmCo is more suitable for working in a high temperature environment.
Features of Samarium Cobalt (SmCo) magnets
1)Constitution: 35% Sm, 60% Co and 5% Fe & Cu
2)SmCo Magnet(Samarium Cobalt magnet) has superior resistance to high temperature(max temp reaches 350-degree centigrade). When working at above 180-degree centigrade, its maximum energy product BH and temperature stability are superior to NdFeB magnet.
2)Excellent resistance to corrosion, no coating is needed for the surface protection.
3)SmCo is suitable for machines with high magnetic requirements and good for strict working environment requirements
4)All sorts of SmCo are used in the electronic magnetron, magnetic transmission, magnetic treatment, magister, etc
5)Certification: ISO 9001 quality system
