Sm2Fe17B3
metal· JVASP-144563· Sm2Fe17B3
Sm2Fe17B3 is a rare-earth iron boride permanent magnet material combining samarium, iron, and boron in a hard magnetic phase. This compound belongs to the samarium-iron-boron family of high-performance magnets, engineered to deliver strong magnetic properties with improved thermal stability and coercivity compared to conventional ferrite magnets. It is used in applications requiring compact, high-strength magnetic functionality in challenging thermal or structural environments, particularly where space constraints and elevated operating temperatures demand superior performance per unit volume.
