· JVASP-38991· TaNbTc2

TaNbTc2 is a refractory high-entropy alloy (HEA) composed of tantalum, niobium, and technetium-containing phases, belonging to the family of multi-principal-element metallic systems developed for extreme-temperature applications. This material is primarily of research interest rather than established commercial production, aimed at aerospace and energy sectors where conventional superalloys reach their thermal limits. The addition of refractory elements (Ta, Nb) and the multi-component design strategy offer potential for superior creep resistance and oxidation performance at temperatures where nickel-based superalloys and conventional titanium alloys become unsuitable.

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.
