· CoCrN3

CoCrN3 is a cobalt-chromium nitride compound belonging to the family of transition metal nitrides, which are interstitial ceramic materials known for high hardness and wear resistance. This material is primarily investigated in research and coating applications where extreme surface hardness, corrosion resistance, and thermal stability are required; it represents an emerging alternative to conventional hard coatings like CrN and TiN, particularly for applications demanding both wear protection and chemical resistance in demanding environments.

Safety & Biocompatibility

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.
