AlCuAu2

AlCuAu2 is a ternary intermetallic compound combining aluminum, copper, and gold in a fixed stoichiometric ratio. This material belongs to the family of precious-metal-containing intermetallics, which are primarily of research and specialized industrial interest rather than mainstream engineering use. AlCuAu2 is encountered in jewelry alloy development, electrical contact applications, and fundamental materials science studies of phase stability in Al-Cu-Au systems, where the presence of gold provides enhanced corrosion resistance and wear properties compared to binary Al-Cu alloys, though cost typically limits adoption to high-value or performance-critical applications.
