· JVASP-19808· ZnAu

ZnAu is an intermetallic compound combining zinc and gold, belonging to the family of precious metal alloys. This material is primarily explored in research and specialized industrial contexts where the unique combination of gold's corrosion resistance and chemical inertness with zinc's availability offers advantages over pure gold in cost-sensitive applications. ZnAu is notable for applications requiring excellent biocompatibility and corrosion resistance in constrained thermal or mechanical environments, though it remains less common than established alternatives like conventional gold alloys or gold-based composites.
