· Sc2 Al1 Ir1

Sc2Al1Ir1 is an experimental intermetallic compound combining scandium, aluminum, and iridium—a research-phase material within the high-performance intermetallic family. This ternary composition is primarily of academic and materials research interest, as it combines the lightweight benefits of aluminum with the refractory and corrosion-resistant properties of iridium and scandium, making it a candidate for extreme-environment applications. Industrial adoption remains limited; the material is typically investigated for potential use in aerospace and high-temperature structural applications where conventional alloys reach their thermal or weight limits.
