Abstract:
1. A method comprising: producing a first aluminum alloy having a horizontal upper surface; heating the first aluminum alloy to a first temperature to form a heated first aluminum alloy, wherein the first temperature is at least about 5° C. lower than the eutectic temperature of the first aluminum alloy; producing a liquid second aluminum alloy; heating the liquid second aluminum alloy to a second temperature wherein the second temperature is at least about 5° C. higher than the liquidus temperature of the second aluminum alloy; and contacting the liquid second aluminum alloy with the horizontal upper surface of the heated first aluminum alloy thereby producing a first multi-layered aluminum alloy product, wherein the heating the first aluminum alloy step occurs before the contacting step.
