· JVASP-100341· Ta3B4W3

Ta3B4W3 is a refractory metal boride compound combining tantalum, boron, and tungsten—a material class designed to withstand extreme temperatures and harsh chemical environments. This is primarily a research and development composition rather than an established commercial alloy; materials in this family are investigated for ultra-high-temperature applications where conventional superalloys reach their limits. The synergistic combination of these refractory elements offers potential for applications demanding exceptional hardness, oxidation resistance, and thermal stability, though engineering adoption remains limited and material characterization is ongoing.

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.
