Ta2NbIr
metal· JVASP-41034· Ta2NbIr
Ta2NbIr is a ternary refractory metal alloy combining tantalum, niobium, and iridium—three elements prized for their exceptional high-temperature stability and corrosion resistance. This composition represents a research-stage material in the family of high-entropy and multicomponent refractory alloys, designed to maintain strength and oxidation resistance at extreme temperatures well beyond conventional superalloys. While not yet widely deployed in production, Ta2NbIr targets applications where standard nickel-based superalloys fail, particularly in aerospace propulsion, thermal protection systems, and advanced energy conversion where material stability above 1600 °C becomes critical.

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.
