Abstract: The invention relates to an extrados structural element made from an aluminum, copper and lithium alloy and a method for manufacturing same. In the method according to the invention, an alloy with composition (in wt %) 4.2 to 5.2 Cu, 0.9 to 1.2 Li, 0.1 to 0.3 Ag, 0.1 to 0.25 Mg, 0.08 to 0.18 Zr, 0.01 to 0.15 Ti, optionally up to 0.2 Zn, optionally up to 0.6 Mn, an Fe and Si content level less than or equal to 0.1% each, and other element with a content level less than or equal to 0.05% each and 0.15% in total, the aluminum is poured, homogenized, deformed hot and optionally cold, placed in a solution at a temperature of at least 515° C., pulled from 0.5 to 5% and annealed. The combination in particular of the magnesium, copper and manganese content with the temperature in solution can reach a very advantageous elasticity under compression limit. Thus, the products according to the invention having a thickness of at least 12 mm have an elasticity under compression limit in the longitudinal direction of at least 645 MPa and an elongation in the longitudinal direction of at least 7%.
