· JVASP-93821· As2W

As₂W is an intermetallic compound combining arsenic and tungsten, belonging to the family of refractory metal arsenides. This material is primarily of research and specialized industrial interest rather than a commodity engineering metal, valued for its potential in high-temperature applications and electronic/photonic devices where tungsten's thermal stability can be leveraged in conjunction with arsenic's semiconducting properties.

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.
