ScAlIr2 is a ternary intermetallic compound combining scandium, aluminum, and iridium, representing an experimental high-performance alloy in the refractory metal family. This material is primarily of research interest rather than established industrial production, investigated for applications requiring exceptional stiffness and thermal stability at elevated temperatures where conventional alloys degrade. The incorporation of iridium—a platinum-group metal—and scandium enables potential use in extreme-environment aerospace and energy systems, though engineering adoption remains limited pending scale-up, cost reduction, and validation of manufacturing feasibility.
