ScAl3
metal· ScAl3
ScAl3 is an intermetallic compound combining scandium and aluminum, belonging to the family of lightweight metallic compounds with ordered crystal structures. This material is primarily of research and developmental interest rather than established in high-volume industrial production, investigated for potential applications where high stiffness-to-weight ratios and thermal stability are advantageous. Engineers consider ScAl3 in advanced aerospace and structural applications where scandium's premium cost is justified by performance gains, though commercial adoption remains limited compared to conventional aluminum alloys and titanium-based 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.
