Sc2AlAu
metal· 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.
