· JVASP-127032· Cu3W

Cu3W is an intermetallic compound combining copper and tungsten, belonging to the family of refractory metal composites. This material is primarily of research and specialized industrial interest, valued for applications requiring high thermal conductivity combined with tungsten's refractory properties, though it remains less common than conventional copper-tungsten pseudoalloys or pure tungsten in production use.

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.
