· JVASP-143655· Ta3Cr3N

Ta₃Cr₃N is a ternary metal nitride compound combining tantalum, chromium, and nitrogen, belonging to the transition metal nitride family. This material is primarily of research and development interest for wear-resistant coatings and hard surface applications, where the combination of tantalum's high density and hardness with chromium's corrosion resistance offers potential advantages over binary nitrides. Engineers would consider this compound for extreme environment applications requiring simultaneous resistance to mechanical wear, thermal stress, and chemical attack.

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.
