NbIr is an intermetallic compound composed of niobium and iridium, belonging to the family of refractory metal alloys. This material combines the high-temperature strength of niobium with the oxidation resistance and density of iridium, making it a candidate for extreme-environment applications where conventional superalloys reach their limits. NbIr is primarily of research and development interest rather than established high-volume production, with potential applications in aerospace propulsion systems, nuclear reactors, and other thermal-mechanical environments requiring both structural stability and corrosion resistance at elevated temperatures.
