Al2Ni2Ir

Al2Ni2Ir is an intermetallic compound combining aluminum, nickel, and iridium in a defined stoichiometric ratio. This material exists primarily in the research domain rather than established industrial production, belonging to the family of ternary intermetallics that combine lightweight aluminum with refractory and noble metals to achieve enhanced high-temperature stability and oxidation resistance. Interest in such compounds centers on aerospace and power-generation applications where conventional superalloys reach performance limits, though development remains largely experimental due to processing challenges, brittleness concerns typical of intermetallics, and cost considerations from iridium content.
