· JVASP-110026· Ta2MoW

Ta2MoW is a refractory metal alloy combining tantalum, molybdenum, and tungsten—three of the highest-melting-point metallic elements. This material belongs to the refractory alloy family and is designed to retain strength and resist oxidation at extreme temperatures where conventional superalloys fail. The alloy is primarily explored in aerospace and high-temperature engineering applications, particularly for components exposed to sustained thermal stress such as rocket nozzles, hypersonic vehicle structures, and advanced turbine systems; its appeal lies in maintaining mechanical integrity at temperatures exceeding those practical for nickel-based superalloys, though it remains relatively specialized and may require careful processing and environmental protection due to the oxidation sensitivity typical of tungsten-containing systems.

Export Control

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.
