· JVASP-39292· Hg3Au

Hg₃Au is an intermetallic compound combining mercury and gold, belonging to the class of heavy metal alloys with exceptional density. This material exists primarily in research and specialized applications rather than as a commodity engineering material, with its properties driven by the unique characteristics of both constituent elements—particularly mercury's extreme density and gold's chemical stability and malleability.

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.
