W2N3
metal· JVASP-102165· W2N3
W2N3 is a tungsten nitride ceramic compound that belongs to the refractory metal nitride family, known for extreme hardness and thermal stability at elevated temperatures. While primarily of research and materials science interest rather than established commercial production, tungsten nitrides are investigated for wear-resistant coatings, hard-facing applications, and high-temperature structural components where conventional metals fail. Engineers consider this material class when designing systems that must withstand severe abrasion, thermal cycling, or corrosive environments beyond the limits of steels and standard superalloys.

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.
