Cr1 N1
semiconductor· Cr1 N1
CrN (chromium nitride) is a hard ceramic coating material belonging to the transition metal nitride family, known for its excellent hardness and wear resistance combined with good corrosion resistance. It is widely used in industrial applications requiring surface protection, particularly in cutting tools, dies, and wear-resistant coatings where it provides superior performance over uncoated substrates or softer alternatives like TiN. The material is valued for enabling longer tool life and faster machining operations while maintaining dimensional stability in aggressive chemical environments.

Export Control
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.
