· Al8 Ca1 Cu4

Al8Ca1Cu4 is an experimental aluminum-based alloy containing calcium and copper as primary alloying elements, representing a research composition in the Al-Ca-Cu system. While not a conventional commercial alloy, this composition family is investigated for potential lightweight structural applications where calcium's role in grain refinement and copper's strengthening contributions could be leveraged. This alloy type remains largely in development phase and would appeal to researchers exploring novel strengthening mechanisms in aluminum systems for aerospace, automotive, or high-performance applications where unconventional element combinations might unlock previously unavailable property combinations.

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.
