· JVASP-117193· TaCrNi

TaCrNi is a refractory high-entropy alloy combining tantalum, chromium, and nickel, designed to maintain strength and oxidation resistance at elevated temperatures where conventional superalloys may degrade. This material family is primarily of research and development interest for aerospace and energy applications, offering potential advantages in extreme thermal environments, though industrial deployment remains limited compared to established nickel-based or cobalt-based superalloys.

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.
