ABSTRACT:
Methods for the improvement of mechanical properties of aluminum can stock materials. In one method, an aluminum alloy is cast into an ingot, heated at an elevated temperature to homogenize the alloy, hot rolled at an elevated temperature to form hot band material and cold rolled to final gauge. After the heating step, the alloy is hot rolled immediately to minimize the cooling of the alloy between the heating and hot rolling steps.
