· JVASP-18614· ScInAu2

ScInAu2 is an intermetallic compound composed of scandium, indium, and gold, belonging to the class of metallic intermetallics that combine precious and rare-earth elements. This is a specialized research material studied for its unique combination of mechanical and electronic properties; it is not currently used in mainstream industrial production. The material's potential lies in advanced applications requiring high stiffness, controlled damping, or specific electronic behavior, though practical adoption depends on cost-effectiveness and scalability relative to conventional alternatives.
