ScAu is an intermetallic compound combining scandium and gold, representing a specialized alloy from the transition metal family with potential for high-performance applications requiring exceptional stiffness and density characteristics. This material is primarily of research and developmental interest rather than established in high-volume industrial production; it belongs to a class of rare-earth and precious-metal intermetallics being investigated for applications where conventional alloys cannot meet demanding mechanical or functional requirements. Engineers would consider ScAu in specialized contexts—such as aerospace, high-precision instruments, or advanced electronics—where the unique combination of scandium's lightweight strength and gold's stability, conductivity, and corrosion resistance offers advantages over conventional titanium alloys, aluminum composites, or pure precious metals.
