Abstract

The present invention relates to a cold-rolled aluminum-alloy sheet having a high strength and a good formability required for producing a DI can. The sheet according to the present invention contains 0.1-2.0% Mn, 0.1-2.0% Mg, and 0.1 to 0.5% Si, has a thickness of 0.4 mm or less. The present invention is characterized by holding a sheet to a temperature of from 80.degree. to 150.degree. C., when it is already heat treated at 400.degree.-580.degree. C. and it is not yet finally cold-rolled. The sheet according to present invention is finally cold-rolled and has a fine grain size.
