Abstract

An aluminum strip for lithographic printing plate supports, from which printing plate supports can be produced with an improved roughenability and at the same time improved mechanical properties, particularly after a burn-in process, is formed of an aluminum alloy which has the following proportions of alloy constituents in wt. %: 0.05%≦Mg≦0.3%, 0.008%≦Mn≦0.3%, 0.4%≦Fe≦1%, 0.05%≦Si≦0.5%, Cu≦0.04%, Ti≦0.04%, inevitable impurities individually max. 0.01%, in total max. 0.05% and remainder Al.
