Cu7Hg6
metal· Cu7Hg6
Cu7Hg6 is an intermetallic compound in the copper-mercury system, representing a brittle metallic phase formed under specific compositional and thermal conditions. This material is primarily of research and historical interest rather than mainstream engineering use, as mercury-containing compounds are increasingly restricted or eliminated from industrial applications due to toxicity and environmental concerns. While copper-mercury phases were historically investigated for specialized electrical contacts and amalgam applications, Cu7Hg6 has largely been superseded by mercury-free alternatives in modern engineering practice.

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.
