· JVASP-16714· CuAs

CuAs is a copper-arsenic intermetallic compound that belongs to the class of binary metal systems with defined stoichiometry. This material is primarily of research and specialized industrial interest rather than a commodity engineering material, valued for its electrical and thermal properties in niche applications where copper's conductivity must be modified or where arsenic-bearing phases naturally occur.

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.
