· JVASP-109513· Co3Ir

Co₃Ir is an intermetallic compound combining cobalt and iridium in a 3:1 atomic ratio, belonging to the class of high-density metallic intermetallics. This material is primarily of research and development interest rather than established production use, with potential applications in high-temperature structural applications and wear-resistant components where the combination of cobalt's magnetic properties and iridium's exceptional hardness and corrosion resistance could be leveraged.
