TaB4W3
metal· JVASP-100801· TaB4W3
TaB4W3 is a refractory metal boride compound combining tantalum, boron, and tungsten—materials known for exceptional hardness and thermal stability. This is a research or specialized-use composition rather than a commodity alloy; the tantalum-boron-tungsten system is investigated for applications requiring extreme hardness, high-temperature strength, and wear resistance beyond what conventional tool steels or single-phase borides can provide. Engineers would consider this material where ultra-hard cutting tools, thermal barrier coatings, or high-stress refractory applications demand superior performance in harsh environments.

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.
