· JVASP-124337· CuHg

CuHg is a copper-mercury intermetallic compound representing a binary metallic system with historical significance in amalgamation and specialty metal applications. This material belongs to the family of mercury-based alloys, which have seen limited modern use due to mercury's toxicity and regulatory restrictions, though CuHg and related compounds remain relevant in specialized electrical contacts, dental amalgam formulations (historically), and research into phase diagrams of immiscible metal systems. Engineers would consider this material primarily in legacy system maintenance, niche electrical applications requiring specific contact properties, or fundamental materials research contexts rather than new product development.

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.
