Abstract
The invention relates to a method for manufacturing an aluminum alloy product including the steps of: creating a bath of liquid metal in an aluminum-copper-lithium alloy, casting said alloy by vertical semi-continuous casting so as to obtain a plate with thickness T and width W such that, during solidification, the hydrogen content of said liquid metal bath (1) is lower than 0.4 ml/100 g, the oxygen content above the liquid surface (14, 15) is less than 0.5% by volume.
