· JVASP-39109· Sc2AlIr

Sc2AlIr is an intermetallic compound combining scandium, aluminum, and iridium, belonging to the class of high-performance metallic materials designed for extreme environments. This material is primarily of research and development interest rather than established production use, with potential applications in aerospace and high-temperature engineering where combinations of strength, stiffness, and thermal stability are critical. The inclusion of iridium—a precious refractory metal—makes this alloy notable for specialized applications where conventional superalloys or titanium alloys reach their performance limits, though cost and manufacturability remain significant considerations relative to alternatives.
