Abstract (en)

[origin: WO2020074818A1] The invention relates to a thin metal sheet which is made of an alloy based on substantially recrystallized aluminum and which has a thickness of 0.25 to 12 mm, the alloy comprising, in percent by weight, Cu 3.4-4.0; Mg 0.5–0.8; Mn 0.1–0.7; Fe ≤ 0.15; Si ≤ 0.15; Zr ≤ 0.04; Ag ≤ 0.65; Zn ≤ 0.5; inevitable impurities ≤ 0.05 each and ≤ 0.15 in total, the remainder consisting of aluminum. The invention also relates to a process for manufacturing such a metal sheet and to the use thereof as a fuselage panel or sheet metal for the production of composite products such as fiber metal laminates (FML) for wing or fuselage applications in the aeronautical industry.
