Cold-rolled aluminum alloy sheet for bottle can

摘要

The present invention reduces the cost of production of a cold-rolled aluminum alloy sheet to be used as a material for bottle cans and reduces the width-direction unevenness of earing. This cold-rolled aluminum alloy sheet for bottle cans has a specific composition and has a structure which contains a small amount of dispersed particles having a center-of-gravity diameter less than 1 µm, which represent anαphase, and in which the ratio of the amount of theβphase that is an Al
