SmFe12
metal· JVASP-37997· SmFe12
SmFe12 is an intermetallic compound composed of samarium and iron, belonging to the rare-earth iron family of magnetic materials. It is primarily investigated as a potential permanent magnet material and is used or studied in applications requiring high magnetic performance at elevated temperatures. SmFe12-based compounds are of significant research interest as a lower-cost alternative to traditional rare-earth magnets (such as Nd-Fe-B), offering potential advantages in thermal stability and abundance, though commercial adoption remains limited compared to established magnet systems.

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.
