钐钴磁性仅次于ND-Fe-b磁铁的耐温性

Samarium cobalt (SmCo) depending on the ingredients include SmCo5 and Sm2Co17, respectively, great for first generation and second generation of rare earth permanent magnet materials. Because of its raw materials are scarce, expensive and its development is restricted. Samarium cobalt (SmCo) as the second generation of rare earth permanent magnet, not only has a high energy product (14-28MGOe) and credible coercive force, and showed a good temperature characteristics in a series of rare-earth permanent magnet. Compare with neodymium-iron-boron, samarium cobalt is more suitable for working in high temperature environments (>200度）。最高使用温度可达380度且磁性能稳定不易退磁。
