· JVASP-101667· ZrTaCr4

ZrTaCr4 is a refractory metal alloy combining zirconium, tantalum, and chromium, designed for extreme high-temperature and corrosive environments where conventional superalloys reach their limits. This material family is primarily explored in aerospace and nuclear research contexts, with potential applications in rocket engine components, plasma-facing materials, and advanced reactor systems where superior oxidation resistance and thermal stability are critical. The tantalum-zirconium base provides exceptional melting points and creep resistance, while chromium additions enhance oxidation protection—making it notable for applications requiring both thermal performance and chemical durability beyond what nickel or cobalt-based alternatives can deliver.

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.
