Abstract
The invention relates to an aluminium alloy for the production of lithographic printing plate supports and also to an aluminium strip produced from the aluminium alloy, a process for the production of the aluminium strip and also its use for the production of lithographic printing plate supports. The object of providing an aluminium alloy as well as an aluminium strip from an aluminium alloy that permits the production of printing plate supports having improved bending-strength fatigue transverse to the rolling direction without adversely affecting the tensile strength values before and after the annealing process and while preserving the roughening properties, is achieved by the fact that the aluminium alloy contains the following alloy components in weight percent:
