CrIr3 is an intermetallic compound combining chromium and iridium in a 1:3 stoichiometric ratio, belonging to the family of refractory transition-metal intermetallics. This material is primarily investigated in research contexts for high-temperature structural applications, leveraging iridium's exceptional thermal stability and corrosion resistance alongside chromium's strength contribution. Engineers consider CrIr3 for extreme-environment scenarios where conventional superalloys reach their limits, though commercial adoption remains limited due to cost, processing complexity, and the material's brittleness at lower temperatures—making it more relevant to aerospace and materials research than mainstream industrial production.
