· JVASP-141092· Ta4Ni2N

Ta₄Ni₂N is a transition metal nitride intermetallic compound combining tantalum and nickel with nitrogen. This material belongs to the family of refractory metal nitrides, which are primarily investigated in research and materials development contexts for their potential to deliver high hardness, thermal stability, and oxidation resistance. While not yet widely deployed in mainstream industrial production, materials in this class show promise for wear-resistant coatings, high-temperature structural applications, and specialized tooling where conventional superalloys or carbides reach their performance limits.

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.
