Cr₃Ir is an intermetallic compound combining chromium and iridium in a 3:1 stoichiometric ratio, forming a hard, dense metallic phase. This material belongs to the family of refractory intermetallics and is primarily of research and development interest rather than established high-volume industrial use. The chromium-iridium system is explored for high-temperature structural applications where both hardness and thermal stability are critical, leveraging iridium's exceptional corrosion resistance and high melting point alongside chromium's hardening capability.
