· JVASP-124320· AlHg

AlHg is an aluminum-mercury intermetallic compound or amalgam system that forms when mercury contacts aluminum, creating a phase that differs significantly from pure aluminum. This material has limited commercial use today due to mercury's toxicity and environmental concerns, though it remains of academic and historical interest in materials science research, particularly in understanding intermetallic formation and phase behavior in metal-mercury systems.

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.
