Abstract (en)

[origin: EP2192202A1] The aluminum alloy (11) comprises alloy components having iron (0.4-0.65 wt.%), magnesium (0.4-0.65 wt.%), silicon (0.05-0.25 wt.%), manganese (0.08 wt.%), copper (0.04 wt.%), titanium (0.05 wt.%), zinc (0.05 wt.%), chromium (0.01 wt.%), residues of aluminum and unavoidable impurities of no more than 0.01 wt.% each and no more than 0.05 wt.% in total. Independent claims are included for: (1) an aluminum strip for producing lithographic printing plate supports; and (2) a method for producing an aluminum strip.
