Abstract (en)

[origin: EP2243849A1] Aluminum alloy comprises (in wt.%): iron (less than 0.4); magnesium (0.41-0.7); silicon (0.05-0.25); manganese (0.1-0.6); copper (= 0.04); titanium (less than 0.1); zinc (= 0.1); chromium (= 0.1); and balance amount includes aluminum and unavoidable impurities each more than 0.05% to give a total of maximum 0.15%. Independent claims are included for: (1) an aluminum strip, for manufacturing lithographic printing plate support, made from the above aluminum alloy with a thickness of 0.15-5 mm; and (2) manufacturing aluminum strips comprising the above aluminum alloy comprising casting a ingot, homogenizing the ingot at 450-610[deg] C, hot-rolling the ingot to a thickness of 2-9 mm and cold-rolling the ingot with or without intermediate annealing to a thickness of 0.15-0.5 mm.
