Al5Ni3Ir2

Al5Ni3Ir2 is an intermetallic compound combining aluminum, nickel, and iridium—a research-phase material rather than a widely commercialized alloy. This composition belongs to the family of high-temperature intermetallics and precious-metal strengthened systems, of interest primarily in academic and advanced materials development for extreme-environment applications. The addition of iridium (a refractory precious metal) to an Al-Ni base suggests exploration of enhanced high-temperature strength, oxidation resistance, and potentially improved ductility compared to simpler Al-Ni intermetallics, though such materials remain largely experimental and face cost and scalability barriers for mainstream industrial adoption.
