A COLD-ROLLED ALUMINUM-ALLOY SHEET FOR FORMING AND PROCESS FOR PRODUCING THE SAME ABSTRACT OF THE DISCLOSURE 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 charac- terized by holding a sheet to a temperature of from 80 to 150°C, when it is already heat treated at 400 - 580°C and it is not yet finally cold-rolled.
