· JVASP-127366· TaCr

TaCr is a tantalum-chromium alloy that combines the high-temperature strength and corrosion resistance of tantalum with chromium's oxidation resistance and hardness. This material targets extreme-environment applications where conventional superalloys face limitations, particularly in aerospace and chemical processing where thermal stability and chemical inertness are critical. The alloy is notably more resistant to corrosive media than single-phase tantalum while maintaining superior high-temperature performance compared to chromium-based alternatives.

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.
