· Sc2Al

Sc₂Al is an intermetallic compound combining scandium and aluminum, belonging to the family of lightweight metallic materials with potential for advanced structural applications. This material exhibits characteristics typical of scandium-aluminum intermetallics—a research-stage material family valued for their combination of low density and moderate stiffness. While not yet widely deployed in mainstream production, Sc₂Al and related compounds are investigated for aerospace and high-performance applications where weight reduction and thermal stability are critical, though current limited availability and cost restrict practical adoption compared to conventional aluminum alloys or titanium.

Regulatory Screening

Environmental

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.
