ScSiAu is an experimental intermetallic compound combining scandium, silicon, and gold in a metallic matrix system. This material belongs to the family of lightweight, high-stiffness intermetallics and is primarily of research interest rather than established industrial production. The scandium-silicon-gold system is investigated for potential applications requiring combinations of low density with high elastic stiffness, making it relevant to aerospace and high-performance structural applications where weight reduction is critical.
