AgHg
metal· JVASP-50703· AgHg
AgHg is a silver-mercury intermetallic compound or amalgam-based alloy system, combining precious metal and liquid metal characteristics. Historically used in dental amalgam formulations and specialized amalgam electrodes, AgHg alloys are encountered in legacy dental applications and electrochemistry contexts, though mercury-based materials have been progressively phased out in modern dentistry due to biocompatibility and environmental concerns. Engineers selecting this material should recognize it primarily as a historical reference point; contemporary practice favors mercury-free alternatives for most applications.

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.
