metal· 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.
