· CrWN2

CrWN2 is a ternary ceramic nitride compound combining chromium, tungsten, and nitrogen, belonging to the family of hard ceramic coatings and advanced refractory materials. This material is of research and emerging industrial interest for hard-facing and wear-resistant applications where high hardness and thermal stability are required, such as cutting tool coatings, wear protection layers, and high-temperature structural components. Its appeal lies in combining the hardness benefits of transition metal nitrides with potential for improved oxidation resistance and toughness compared to simpler binary nitride systems.

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.
