· JVASP-121667· Co5CuN4

Co5CuN4 is a cobalt-copper nitride intermetallic compound that combines the hardness and wear resistance of cobalt with copper's thermal and electrical conductivity. This material exists primarily in research and experimental contexts, where it is being investigated for applications requiring enhanced hardness, corrosion resistance, or functional properties at the intersection of refractory metals and nitride ceramics. The cobalt-copper-nitrogen system offers potential advantages over conventional cobalt alloys or pure nitride ceramics, though industrial adoption remains limited pending further development and cost optimization.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
