Al14 Er2 Au6

Al₁₄Er₂Au₆ is an intermetallic compound combining aluminum, erbium (a rare earth element), and gold in a fixed stoichiometric ratio. This is a research-phase material rather than a commercially established alloy; such rare-earth-containing aluminum intermetallics are typically studied for potential high-temperature structural applications or specialized functional properties where the rare earth additions modify phase stability and mechanical behavior.
