SmFe2
metal· JVASP-19950· SmFe2
SmFe2 is an intermetallic compound composed of samarium and iron, belonging to the rare-earth iron intermetallic family. This material is primarily of research and specialized industrial interest, valued for its magnetic properties inherent to rare-earth iron systems, making it relevant for permanent magnet applications and magnetic device design. SmFe2 represents a lower-cost alternative to some rare-earth magnets while offering distinct phase stability and magnetic characteristics compared to other samarium-iron compositions.

Export Control
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.
