· TaW3

TaW3 is a refractory intermetallic compound composed of tungsten and tantalum, belonging to the family of high-melting-point metal compounds used in extreme-temperature and high-stress applications. This material is primarily investigated in research and specialized industrial contexts for applications demanding exceptional hardness, wear resistance, and thermal stability at elevated temperatures. Its appeal lies in combining tungsten's hardness with tantalum's corrosion resistance, making it a candidate for applications where conventional alloys fail, though it remains less widely deployed than established superalloys due to processing complexity and brittleness management challenges.

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.
