PROBLEM TO BE SOLVED: To provide an aluminum alloy sheet for a bottle can in which surface roughening is less liable to occur at the chime parts of the bottom, and wrinkles is less liable to be formed in neck forming. SOLUTION: The aluminum alloy sheet has a composition comprising, by weight, 0.2 to 0.4% Si, 0.25 to 0.55% Fe, 0.15 to 0.35% Cu, 0.7 to 1.2% Mn, 0.8 to 1.4% Mg, 0.10 to 0.3% Zn and 0.01 to 0.15% Ti, and the balance Al with inevitable impurities. The crystal grain size in the sheet thickness direction is≤10μm. COPYRIGHT: (C)2005,JPO&NCIPI
