· JVASP-41220· Mg2AgAu

Mg₂AgAu is an intermetallic compound combining magnesium with silver and gold, representing a ternary metal system in the lightweight magnesium family. This material is primarily of research and academic interest rather than established in high-volume production; it exemplifies the exploration of noble-metal-reinforced magnesium systems that seek improved strength, corrosion resistance, or functional properties beyond conventional Mg alloys. The addition of precious metals to magnesium matrices is driven by applications requiring specialized combinations of low density, elevated-temperature stability, or biocompatibility, though cost and processing complexity typically limit deployment to niche aerospace, biomedical, or high-performance electronics contexts.
