· Al8 Sc1 Fe4

Al8Sc1Fe4 is an aluminum-based intermetallic compound containing scandium and iron additions, classified as a semiconductor material. This is a research-phase alloy designed to explore enhanced mechanical properties and thermal stability through scandium strengthening combined with iron precipitation hardening in aluminum matrices. While not yet widely commercialized, aluminum-scandium-iron compounds are being investigated for aerospace and high-temperature structural applications where improved stiffness-to-weight ratios and thermal resistance could offer advantages over conventional aluminum alloys.

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.
