· CrWN3

CrWN3 is a transition metal nitride compound combining chromium, tungsten, and nitrogen, belonging to the family of refractory metal nitrides. This material is primarily of research interest for hard coatings and wear-resistant applications, where the combination of tungsten and chromium nitrides offers potential improvements in hardness, oxidation resistance, and thermal stability compared to single-component nitride coatings.

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.
