· JVASP-36676· CuNi3N

CuNi3N is a copper-nickel nitride intermetallic compound that combines metallic and ceramic characteristics through nitrogen incorporation into the Cu-Ni system. This material is primarily of research interest in advanced materials development, where nitride-based metallics are investigated for applications requiring enhanced hardness, wear resistance, and thermal stability compared to conventional binary copper-nickel alloys. While not yet widely established in mainstream production, compounds in this family are explored for surface coatings, wear-resistant components, and high-performance applications where the hardening effect of nitrogen can improve performance over unreinforced metal matrices.
