· JVASP-75531· TaAsW

TaAsW is a ternary intermetallic compound combining tantalum, arsenic, and tungsten—a research-phase material rather than a production alloy. This composition belongs to the family of refractory metal compounds being explored for extreme environment applications where conventional alloys reach their performance limits. Its notable density and the properties of its constituent elements (tantalum's corrosion resistance, tungsten's high melting point, and arsenic's electronic properties) suggest potential for high-temperature structural or functional applications, though industrial 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.
