· JVASP-137675· SmYFe17

SmYFe17 is an intermetallic compound in the rare-earth iron family, combining samarium (Sm) and yttrium (Y) with iron (Fe) in a fixed stoichiometric ratio. This material is primarily of research and development interest for permanent magnet applications, where the rare-earth iron backbone offers potential for high magnetic performance at reduced cost compared to conventional rare-earth magnets. SmYFe17 and related ThMn12-type structure compounds are investigated as alternatives to Nd-Fe-B magnets, particularly where thermal stability, corrosion resistance, or material abundance considerations drive material selection.

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.
