· Al4 Au4

Al₄Au₄ is an intermetallic compound composed of aluminum and gold in a 1:1 atomic ratio, representing a research-phase material rather than an established commercial alloy. This compound belongs to the family of precious metal intermetallics, which are of academic and specialized industrial interest for their potential combination of lightweight aluminum with the chemical stability and thermal properties of gold. Applications remain primarily exploratory, with potential relevance in high-reliability electronics, specialized coatings, or catalysis research where the unique electronic properties of the Al-Au system may offer advantages over conventional materials.
