AlCu is an aluminum-copper binary alloy that combines the lightweight characteristics of aluminum with copper's enhanced strength and conductivity. This alloy family is widely used in aerospace structures, electrical conductors, and heat exchangers where a balance of low density, moderate strength, and thermal/electrical performance is required. AlCu alloys are particularly valued in applications demanding weight reduction without sacrificing reliability, though specific composition variants (like the 2xxx series in aerospace) offer superior performance compared to pure aluminum or simple binary alternatives.
