· JVASP-11133· CuBC4N4

CuBC₄N₄ is an experimental copper-boron-carbon-nitrogen compound that belongs to the class of hard ceramic-metallic composites. This material is primarily of research interest rather than established in production, with potential applications in extreme hardness and wear-resistance applications, similar to other transition metal boronitrides and carbides. The material combines metallic copper with a hard ceramic network, making it a candidate for advanced coating, tooling, or structural applications where both thermal conductivity and hardness are desirable.
