<p>In this aluminum alloy sheet, the density of a specific set of atoms is regulated in a cold rolling composition manufactured by controlling isothermal conditions and cold rolling conditions for an ingot when manufacturing the aluminum alloy sheet for a 3000 series DI can with a specific composition, thereby promoting subgraining in a can body composition during a coating baking treatment (heat treatment) after can body formation. Thus, the piercing resistance of a can is made superior even in a severe usage environment with lower internal pressure for the can body which is made thin.</p> |
