Abstract

Aluminum alloy of the AlCuMg type contains alloying additions (in wt.%) of 4.5-5.5 Cu, 0.45-0.65 Mg, maximum 0.2 Si, maximum 0,25 Fe, maximum 0.8 Mn, maximum 0.15 Ti, and optionally 0.12-0.25 Zr, 0.05-0.5 Ag and maximum 0.15 impurities. An Independent claim is also included for the manufacture of a plate made of Al alloy comprising casting an ingot of the alloy, homogenizing the cast ingot, maintaining the ingot at 380-440 degrees C for at least 2.5 hours, hot rolling the ingot to a plate at 380-440 degrees C, solution annealing the plate, quenching, stretching the plate by 1-5%, and hardening the plate.
