· JVASP-35062· SmFeSi

SmFeSi is an intermetallic compound composed of samarium, iron, and silicon, belonging to the rare-earth transition metal alloy family. This material is primarily of research interest for magnetic applications and energy conversion devices, where rare-earth iron silicides are explored for their potential magnetic properties and thermal stability. While not yet widely deployed in high-volume industrial production, SmFeSi represents an emerging class of materials being investigated for specialized electromagnetic and thermoelectric applications where conventional iron-based alloys are insufficient.

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.
