BeAu is an intermetallic compound combining beryllium and gold, representing a specialized metallic material from the beryllium-gold phase diagram. This compound is primarily of research and specialized industrial interest rather than a mainstream engineering material, with applications driven by the unique combination of beryllium's low density and high stiffness alongside gold's chemical stability and biocompatibility. Engineers consider BeAu for niche applications requiring exceptional specific stiffness, corrosion resistance, or compatibility with sensitive environments, though its high density, cost, and toxicity concerns associated with beryllium limit broader adoption.
