· Cu2As

Cu2As is an intermetallic compound combining copper and arsenic, representing a brittle metallic phase that forms in copper-arsenic systems. This material is primarily of research and metallurgical interest rather than a mainstream engineering alloy, encountered in phase studies of Cu-As binary systems and as a minor constituent in specialized copper alloys or semiconductor-related applications.

Export Control

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.
