· Sc2 Al2

Sc₂Al₂ is an intermetallic compound combining scandium and aluminum, representing a lightweight metallic system with potential high-temperature stability due to scandium's refractory character. This material exists primarily in research and development contexts, as it is not yet widely commercialized; the scandium–aluminum family is of interest for aerospace and high-performance applications where weight reduction and thermal resistance are critical, though manufacturing scalability and cost remain significant barriers compared to established titanium or nickel-based alternatives.

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.
