· Sc2 Al1 Cu1

Sc₂Al₁Cu₁ is an intermetallic compound combining scandium, aluminum, and copper—a materials research composition rather than a commercial alloy. This ternary system sits at the intersection of lightweight metallurgy and advanced intermetallic development, where scandium additions to aluminum-copper systems are explored for enhanced strength-to-weight characteristics and potential high-temperature stability. The material remains largely in the research phase; its practical adoption depends on demonstrating cost-effective manufacturing, thermal stability, and performance advantages over established aluminum-copper alloys (2xxx and 7xxx series) in demanding aerospace or automotive applications.

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.
