· JVASP-155656· CaAl2Cu2

CaAl2Cu2 is an intermetallic compound composed of calcium, aluminum, and copper, belonging to the family of lightweight metallic phases that can form in multi-element alloy systems. This material is primarily of research and developmental interest rather than an established commercial product; it appears in the context of advanced aluminum-copper alloy systems where calcium is used as a grain refiner or strengthening addition. The compound's potential relevance lies in aerospace and automotive lightweighting applications where engineers seek to combine low density with improved mechanical or thermal properties, though its practical adoption would depend on manufacturability, cost-effectiveness, and performance validation against conventional aluminum alloys and established intermetallics.

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.
