Abstract (en)
[origin: WO2016051099A1] The invention concerns a sheet 0.5 to 9 mm thick, having an essentially recrystallised granular structure made from an aluminium alloy comprising 2.8 to 3.2 % by weight of Cu, 0.5 to 0.8 % by weight of Li, 0.1 to 0.3 % by weight of Ag, 0.2 to 0.7 % by weight of Mg, 0.2 to 0.6 % by weight of Mn, 0.01 to 0.15 % by weight of Ti, a quantity of Zn of less than 0.2 % by weight, a quantity of Fe and of Si of less than 0.1 % each by weight, and inevitable impurities in a content less than or equal to 0.05% each by weight and 0.15% in total by weight, said sheet being obtained by a method comprising pouring, soaking, hot rolling and optionally cold rolling, solution annealing, quenching and tempering. The sheets according to the invention are particularly advantageous for producing aircraft fuselage panels.
