· JVASP-127662· W3N

W3N is a tungsten nitride compound that belongs to the refractory metal nitride family, characterized by extremely high hardness and thermal stability. This material is primarily investigated for wear-resistant coatings, cutting tool applications, and high-temperature structural components where conventional alloys fail. W3N offers exceptional hardness and oxidation resistance, making it particularly valuable in applications demanding extreme durability at elevated temperatures, though it remains largely in advanced research and specialized industrial applications rather than mainstream production.

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.
