ScAu₄ is an intermetallic compound composed of scandium and gold, belonging to the family of rare-earth gold intermetallics. This is a research-phase material with potential applications requiring high stiffness and density in compact form factors, though industrial adoption remains limited due to cost, scarcity of scandium, and processing challenges. Engineers would consider this material primarily in advanced aerospace, electronics, or specialized medical applications where the unique combination of scandium's light-element properties and gold's chemical stability offers advantages over conventional alloys.
