· JVASP-125002· Ar3Au

Ar3Au is an intermetallic compound in the gold-based alloy family, formed from the reaction between gold and a lighter element. This compound represents the research and development space of gold intermetallics, which are explored for applications requiring exceptional corrosion resistance combined with metallic properties. While not a commodity engineering material, gold intermetallics are studied for specialized applications where corrosion immunity and chemical inertness justify material cost.

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.
