TaW
metal· JVASP-106329· TaW
TaW is a refractory metal alloy combining tantalum and tungsten, two of the highest melting-point elements in the periodic table. This material is engineered for extreme-temperature applications where conventional metals fail, and is valued in aerospace, electronics, and specialized industrial sectors for its exceptional thermal stability and resistance to oxidation at elevated temperatures. Engineers select TaW-based materials when operating conditions demand reliability above ~2000°C or when weight-critical designs require a dense, high-stiffness system that can withstand thermal cycling without degradation.

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.
