Abstract
System and method of producing multi-layered aluminum alloy products are disclosed. A multi-layered aluminum alloy product may be formed by first heating a first aluminum alloy to a first temperature where the first temperature is at least about 5° C. lower than the eutectic temperature of the first aluminum alloy, second heating a second aluminum alloy to a second temperature where the second temperature is at least about 5° C. higher than the liquidus temperature of the second aluminum alloy, and coupling the second aluminum alloy to the first aluminum alloy to produce a multi-layered aluminum alloy product.
Claims15
A method comprising:
- producing a first aluminum alloy having a horizontal upper surface;
- producing a second aluminum alloy;
- heating the second aluminum alloy to a first temperature to form a liquid second aluminum alloy, wherein the first temperature is at least 1° C. higher than the liquidus temperature of the second aluminum alloy;
- delivering the liquid second aluminum alloy to the horizontal upper surface of the first aluminum alloy while the first aluminum alloy is substantially stationary;
- and
- contacting the liquid second aluminum alloy with the first aluminum alloy to form a first multi-layered aluminum alloy product.
