摘要： A method of manufacturing an AA2xxx-series aluminium alloy plate product having improved fatigue failure resistance and a reduced number of flaws, the method comprising the following steps (a) casting an ingot of an aluminium alloy of the 2xxx-series, the aluminium alloy comprising (in wt. %): Cu 1.9 to 7.0, Mg 0.3 to 1.8, Mn up to 1.2, balance aluminium and impurities, each 0.05 max, total 0.15; (b) homogenizing and/or preheating the cast ingot; (c) hot rolling the ingot into a plate product by rolling the ingot with multiple rolling passes characterized in that, when at an intermediate thickness of the plate between 100 and 200 mm, at least one high reduction hot rolling pass is carried out with a thickness reduction of at least 15%; wherein the plate product has a final thickness of less than 60 mm. The invention is also related to an aluminium alloy product produced by this method.
