· Sm1 Fe1 C2

SmFe₂C (samarium iron carbide) is an intermetallic compound belonging to the rare-earth transition metal carbide family, characterized by strong metallic bonding and potential magnetic properties due to its samarium and iron constituents. This material is primarily of research interest for high-strength structural applications and magnetic device components, where the combination of rare-earth and ferrous elements offers potential advantages in hardness and thermal stability compared to conventional carbides or iron-based alloys. SmFe₂C represents an experimental composition within rare-earth carbide systems being investigated for specialized engineering applications where extreme hardness, wear resistance, or specific magnetic behavior is required.

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.
