TaNiAs
metal· JVASP-147462· TaNiAs
TaNiAs is a ternary intermetallic compound composed of tantalum, nickel, and arsenic. This material belongs to the class of high-density metallic compounds and is primarily of research interest rather than established commercial production. The material combines the high melting point and corrosion resistance of tantalum with nickel's strength and ductility, making it relevant for extreme-environment applications, though its arsenic content presents handling and environmental considerations that limit widespread adoption compared to more conventional 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.
