AlAu2 is an intermetallic compound combining aluminum and gold in a 1:2 stoichiometric ratio, forming a brittle metallic phase with high density. While not widely used in commodity applications, this material belongs to the Al-Au intermetallic family that has been explored in jewelry alloys, wear-resistant coatings, and specialized bonding applications where gold's nobility and aluminum's light weight offer complementary benefits. The compound's notable elastic anisotropy and relatively high stiffness make it of primary interest to materials researchers investigating phase stability and mechanical behavior in precious-metal systems, rather than to general engineering practice.
