· NbCrN

NbCrN is a ternary nitride ceramic coating combining niobium, chromium, and nitrogen, belonging to the family of transition metal nitrides known for exceptional hardness and wear resistance. It is primarily used as a physical vapor deposition (PVD) coating in cutting tools, forming dies, and wear-critical components in aerospace and automotive manufacturing, where its high hardness and thermal stability outperform conventional TiN or CrN single-element nitride coatings. Engineers select NbCrN when demanding applications require superior resistance to abrasive wear, adhesive wear, and oxidation at elevated temperatures, making it particularly valuable for high-speed machining, stamping dies, and harsh industrial 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.
