· Sc4 Fe4 Si4

Sc₄Fe₄Si₄ is an intermetallic compound combining scandium, iron, and silicon in a 1:1:1 atomic ratio. This is a research-phase material studied primarily in the context of high-strength lightweight alloys and advanced intermetallic systems rather than established commercial use. The scandium-iron-silicon family is of interest for aerospace and high-temperature applications where reduced density combined with structural integrity is valued, though practical engineering adoption remains limited and material processing, reproducibility, and cost considerations are active areas of investigation.

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.
