· 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.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
