Be5Au is an intermetallic compound combining beryllium and gold, belonging to the class of high-performance metallic intermetallics. This material is primarily of research and specialized application interest rather than widespread industrial use, valued for its combination of low density and high stiffness characteristic of beryllium-based systems. Be5Au is considered for aerospace and precision engineering applications where weight reduction and elastic performance are critical, though its limited availability, manufacturing complexity, and the toxicity hazards associated with beryllium processing restrict its practical adoption compared to conventional aluminum or titanium alloys.
