Ir₂W₂ is an intermetallic compound combining iridium and tungsten in an equiatomic composition, representing a high-performance material in the refractory metal alloy family. This material is primarily of research and development interest for extreme-environment applications where both exceptional hardness and thermal stability are critical, such as in aerospace propulsion systems, high-temperature catalysis, and wear-resistant coatings. Engineers would evaluate Ir₂W₂ when conventional superalloys or tungsten-based composites cannot meet simultaneous demands for creep resistance, oxidation resistance, and hardness in temperatures approaching or exceeding 1500°C.
