Abstract
A method of producing aluminum can sheet having low earing characteristics. An aluminum alloy ingot is provided and is heated to a temperature between about 527.degree. to 571.degree. C. (980.degree. to 1060.degree. F.). After this, the ingot is hot rolled in a single-stand reversible hot mill to produce an intermediate gauge sheet. The intermediate gauge sheet is then cold rolled to produce a final gauge aluminum can sheet having low eating characteristics.
