· JVASP-99840· Ta2NbRe

Ta2NbRe is a refractory high-entropy alloy composed of tantalum, niobium, and rhenium—three elements with exceptionally high melting points. This material is primarily investigated in research settings for ultra-high-temperature structural applications where conventional superalloys reach their limits, offering potential advantages in creep resistance and thermal stability at extreme conditions.

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.
