Co2N
metal· Co2N
Co₂N is a cobalt nitride intermetallic compound belonging to the family of transition metal nitrides, which are ceramic-like materials combining metallic and covalent bonding characteristics. This material is primarily of research and emerging industrial interest for applications requiring high hardness, wear resistance, and thermal stability; cobalt nitrides are being investigated as alternatives to traditional hard coatings and tool materials, particularly where corrosion resistance and cost-effectiveness relative to established nitride systems (TiN, CrN) are considerations.

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.
