· JVASP-105259· Ta2TiW

Ta2TiW is a refractory metal intermetallic compound combining tantalum, titanium, and tungsten—elements prized for extreme temperature stability and oxidation resistance. This material belongs to the family of high-entropy and multi-principal element alloys, representing an emerging research composition designed to achieve superior performance in ultra-demanding thermal and mechanical environments where conventional superalloys reach their limits. While primarily in developmental stages, Ta2TiW and related refractory compositions are being investigated for next-generation aerospace propulsion, high-temperature structural applications, and nuclear systems where weight efficiency and thermal creep resistance are critical.

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.
