metal

· ScFeSi

ScFeSi is an intermetallic compound combining scandium, iron, and silicon—a research-stage material belonging to the family of transition metal silicides. This ternary system is primarily of scientific and developmental interest, with potential applications in high-temperature structural materials and magnetic applications, though industrial deployment remains limited compared to established superalloys and conventional alloys.

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.
