· JVASP-110993· TaNbN2

TaNbN2 is a refractory metal nitride compound combining tantalum, niobium, and nitrogen, belonging to the family of transition metal nitrides. This material is primarily of research and development interest for high-temperature and wear-resistant applications, where its multi-element composition offers potential for enhanced hardness, oxidation resistance, and thermal stability compared to single-element 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.
