· Al1 Sc1 Cu2

Al1Sc1Cu2 is an experimental intermetallic compound combining aluminum, scandium, and copper in a defined stoichiometric ratio, classified as a semiconductor material. This composition represents a research-phase alloy system that combines the lightweight properties of aluminum with scandium's strengthening effects and copper's conductivity, potentially offering high specific strength or novel electronic properties depending on crystal structure and processing. Materials in this Al-Sc-Cu family are primarily of academic and advanced materials research interest, with potential applications in next-generation aerospace alloys, high-performance structural-functional hybrids, or specialized electronic devices, though production maturity and commercial viability remain limited.

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.
