· JVASP-85110· Sc2AlAu

Sc2AlAu is an intermetallic compound combining scandium, aluminum, and gold—a ternary metal system that belongs to the family of lightweight, high-performance intermetallics. This is a research-stage material studied for its potential combination of low density with metallic bonding characteristics; it represents exploratory work in advanced alloy design rather than an established commercial product. Applications remain largely experimental, with interest centered on aerospace and high-temperature structural contexts where the scandium-aluminum base offers potential weight savings, though commercial viability and manufacturing scalability remain under investigation.

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.
