· MgAu

MgAu is an intermetallic compound combining magnesium and gold, belonging to the family of lightweight metallic intermetallics. This material is primarily of research and laboratory interest rather than established in high-volume industrial production, being investigated for its potential in applications requiring the low density of magnesium combined with gold's corrosion resistance and chemical stability. Engineers would consider MgAu in specialized contexts where conventional magnesium alloys or gold-based materials fall short—particularly in aerospace, medical device, or electronics applications demanding both weight efficiency and exceptional environmental durability.
