Abstract: An aluminum alloy composition for sheet product consists essentially of 0.3 to 1.1 wt. % silicon, 0.4 to 1.0 wt. % iron, 0.009 to 0.25 wt. % copper and optionally, minor amounts of manganese, magnesium, chromium, zinc, titanium and other incidental impurities with the balance aluminum. In making aluminum sheet from this composition, the aluminum alloy is continuously cast into an intermediate gauge sheet product and directly cold rolled without an intermediate thermal treatment to final gauge. Optionally, the final gauge sheet product can be subjected to a known temper practice. Using the iron, silicon and copper- containing aluminum alloy composition, a sheet product is produced which has acceptable mechanical properties for use as general purpose aluminum sheet, semi-rigid aluminum container stock, consumer wrap container, cutter bars and the like. The figure shows the method steps of fabricating a sheet product.

Abstract: A method of making an aluminum foil product from an aluminum silicon-iron alloy comprises casting the alloy into a slab, preferably by twin roll casting, cold rolling, the alloy to an intermediate gauge and reroll annealing the intermediate gauge material. The reroll annealed material is then cold rolled to a final foil gauge followed by a final recrystallizing anneal. The aluminum alloy has a controlled amount of silicon and iron such that the silicon is equal to or greater than the iron amount and the reroll temperature is 800 DEG F (427 DEG C) or less. The combination of the controlled amounts of silicon and iron and the lower reroll anneal temperature results in an improved foil product in terms of finer grain size and higher elongation which is also less costly to produce.
