Sm2Fe17C
metal· JVASP-143800· Sm2Fe17C
Sm₂Fe₁₇C is an iron-samarium carbide intermetallic compound belonging to the rare-earth transition metal family. This material is primarily of research and specialized industrial interest for its potential as a hard magnetic phase or reinforcing constituent in composite systems, leveraging the strong magnetic coupling between samarium and iron. It appears in advanced magnet alloys and high-performance composite applications where the combination of rare-earth magnetism and carbide hardening offers advantages over conventional materials, though it remains less common than optimized Sm₂Co₁₇ or NdFeB-based systems in volume production.

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.
