· JVASP-104923· TaNbAl6

TaNbAl6 is a refractory high-entropy alloy (HEA) based on tantalum, niobium, and aluminum, designed to combine the high-temperature strength of refractory metals with improved formability and reduced density compared to pure tantalum or niobium. This material family is primarily of research and developmental interest, targeting extreme-environment applications where conventional superalloys reach their performance limits, such as next-generation aerospace propulsion systems, hypersonic vehicle structures, and specialized industrial furnace components.

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.
