· JVASP-101413· Ta2ReW

Ta₂ReW is a refractory metal intermetallic compound combining tantalum, rhenium, and tungsten—three of the highest-melting-point elements in the periodic table. This material belongs to the family of ultra-high-temperature intermetallics developed primarily for aerospace and advanced thermal applications where conventional superalloys reach their limits. Ta₂ReW remains largely in the research and development phase, with potential applications in hypersonic vehicle structures, rocket nozzles, and next-generation turbine engines; its appeal lies in extreme thermal stability and oxidation resistance at temperatures where nickel and cobalt-based superalloys fail, though processing challenges and cost have limited commercial adoption to date.

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.
