ScAlAu2 is an intermetallic compound combining scandium, aluminum, and gold in a ternary phase system. This material belongs to the family of precious-metal intermetallics and is primarily of research and developmental interest rather than an established industrial commodity. The compound is investigated for its potential in high-performance applications where the combination of light aluminum, corrosion-resistant gold, and scandium's strengthening effects may offer advantages in specific aerospace, electronics, or wear-resistant coating contexts.
