· JVASP-102674· TaNbV

TaNbV is a refractory high-entropy alloy composed of tantalum, niobium, and vanadium, representing an emerging class of multi-principal-element metals designed for extreme-temperature and high-strength applications. This alloy family is primarily under investigation in research and development contexts for aerospace, power generation, and defense sectors where conventional superalloys approach their performance limits. The combination of refractory elements provides potential advantages in melting point, oxidation resistance, and strength retention at elevated temperatures compared to traditional nickel- or cobalt-based alternatives, though production and processing challenges currently limit widespread industrial deployment.

Export Control

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.
