Abstract
Aluminum alloy sheet for use in drawn and ironed can bodies, having a content of 0.45-0.8% Mn, 1.1-2.2% Mg, 0.3-1.2% Fe, and 0.1-0.50% Si, produced by casting a continuous strip ingot of the alloy between chilled moving belts while maintaining a heat flux of at least about 40 cal./cm..sup.2 /sec. through the belts such that the as-cast ingot has a cell size ranging from about 10-15 microns at its surfaces to about 23-30 microns at the center of its thickness, and reducing the ingot by rolling operations including cold rolling to can body stock gauge, the cold-rolled product having a maximum constituent particle size of about 2 microns at the surface and about 3-4 microns at the center.
