TaCr2W
metal· JVASP-157200· TaCr2W
TaCr2W is a refractory metal alloy based on tantalum with chromium and tungsten additions, designed for extreme-temperature and corrosion-resistant applications. This composition falls within the family of high-entropy or multi-principal-element refractory alloys, which are pursued in advanced materials research for their potential to combine the high melting points of tantalum and tungsten with improved ductility and workability compared to pure refractory metals. While not a widely commercialized commodity material, alloys in this family are investigated for aerospace propulsion, thermal management in extreme environments, and nuclear applications where conventional superalloys reach their performance limits.

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.
