Description
AA 2050 is a third-generation aluminum-copper-lithium alloy (~3.6% Cu, 0.9% Li) that combines high strength with reduced density compared to conventional 2024. The lithium content lowers density by approximately 3% per weight percent added while also increasing elastic modulus. It is used in aerospace fuselage panels, lower wing skins, and thick plate applications where weight savings are critical.
