· CrWON2

CrWON2 is a ceramic compound in the chromium-tungsten oxynitride family, combining refractory metal elements with oxygen and nitrogen to form a hard ceramic phase. This material is primarily of research interest for high-temperature and wear-resistant applications, where the addition of tungsten and the oxynitride chemistry aim to improve hardness and thermal stability compared to simpler nitride or oxide systems. Its use remains largely experimental, with potential value in cutting tools, coatings, and extreme-environment wear applications where traditional carbides or single-phase nitrides show limitations.

Regulatory Screening

Environmental

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.
