Al3Ir is an intermetallic compound combining aluminum with iridium, belonging to the class of high-performance metallic intermetallics. This material is primarily of research and development interest rather than a mature commercial alloy, studied for applications requiring exceptional hardness, thermal stability, and resistance to oxidation at elevated temperatures. Its iridium content makes it exceptionally expensive and limits widespread adoption, but it is investigated in aerospace and high-temperature structural applications where superior strength retention and chemical inertness justify the material cost.
