· JVASP-126978· Cu3Hg

Cu3Hg is an intermetallic compound composed of copper and mercury, belonging to the family of mercury-based metallic systems. This material is primarily of academic and historical interest rather than widespread industrial use, as mercury-containing alloys face significant regulatory restrictions and health/environmental concerns in modern engineering practice. The compound has been studied in materials research contexts for understanding phase diagrams and intermetallic behavior, but has limited practical application in contemporary engineering due to mercury toxicity and the availability of superior mercury-free alternatives for any application where it might have been considered.

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.
