· ScAu2

ScAu₂ is an intermetallic compound combining scandium and gold, belonging to the rare-earth metallic systems family. This material is primarily of research and experimental interest rather than established industrial production, explored for its potential in high-performance applications where the combination of scandium's light weight and gold's chemical stability and thermal properties may offer unique advantages. While not yet commercially widespread, intermetallic compounds of this type are investigated for aerospace, electronics, and specialized coating applications where material density and mechanical integrity must be carefully balanced.
