补充资料:2:17型稀土钴永磁材料
分子式:
CAS号:

性质:稀土(RE)-Co 2:17型以Sm2Col7为代表。为了提高其性能达到实用化,而添加了铜、铁等多种元素(以R-TM表示),开发了(1)Sm-Co-Cu(2)Sm-Co-Cu Fe(3)Sm-Co-Cu-Fe-M(Zr,Ti,Hf,Ni)等三个系列。称为第二代永磁体。商品化磁能积一般达119~239kJ/m3(15~30MGsOe),低矫顽力类型达398~477kA/m(5~6kOe)。高矫顽力:1194~2388A/m(15~30kOe)。2:17型R-TM含Sm较低。约18%~20%(质量),Co48%~50%(质量),Fe10%~20%(质量),Cu6%~8%(质量),Zr1%~3%(质量)(或Ti,Hf等)。制备方法用途同钕-铁-硼永磁材料。
