Samarium cobalt (SmCo) magnets include 1:5 type (SmCo5) and 2:17 type (Sm2Co17) magnets. Both types of SmCo magnet grades basically include three parts, i.e. “letter 1” + “number” + “letter 2”. The three parts in sintered SmCo magnet grades present material type, (BH)max value (in CGS unit) and Hcj level, respectively. The part “letter 1” are “XG” and “XGS” for sintered SmCo5 and Sm2Co17 magnets, respectively. Besides, the Hcj levels of sintered SmCo5 magnets include “default” (Hcj ≥ 15 kOe)… Read More
