· JVASP-35354· FeCoSn

FeCoSn is a ferromagnetic ternary alloy combining iron, cobalt, and tin, belonging to the family of soft magnetic materials and intermetallic compounds. This composition sits at the intersection of high-performance magnetic alloys and wear-resistant materials, making it of particular interest for applications requiring both electromagnetic functionality and mechanical durability. While not a mainstream commercial alloy, FeCoSn is primarily explored in research contexts for soft magnetic cores, magnetic sensor applications, and high-frequency electromagnetic devices where the tin addition improves corrosion resistance and mechanical properties compared to binary Fe-Co systems.

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.
