· Al2Au

Al₂Au is an intermetallic compound combining aluminum and gold, belonging to the family of binary metallic intermetallics that exhibit ordered crystal structures and intermediate properties between constituent metals. This material is primarily of research and specialized industrial interest rather than high-volume production, valued for applications requiring the unique combination of aluminum's low density with gold's chemical stability and electrical properties. Its use is typically restricted to high-value sectors where gold's corrosion resistance and noble-metal characteristics justify material costs, or in fundamental studies of phase behavior and mechanical performance in Al-Au systems.
