· CuTaN3

CuTaN₃ is a copper-tantalum nitride compound, a transition metal nitride that combines copper and tantalum in a ceramic or intermetallic matrix. This material belongs to the family of refractory nitrides and is primarily of research interest for its potential hardness, wear resistance, and thermal stability, though it remains relatively uncommon in established industrial 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.
