AlAu is an intermetallic compound combining aluminum and gold, forming a metallic phase with ordered crystal structure. This material is primarily of research and specialized industrial interest rather than commodity use, valued in applications where the unique combination of gold's chemical inertness and aluminum's low density offers distinct advantages. AlAu appears in thin-film electronics, specialized coatings, and high-reliability interconnect systems where corrosion resistance, thermal stability, and precise phase control are critical.
