Abstract
An aluminum alloy foil is formed from an alloy containing about 1.2 to 1.7% by weight Fe and about 0.35 to 0.80% by weight Si, with the balance aluminum and incidental impurities. The alloy is continuously strip cast to form a strip having a thickness less than about 25 mm, which is then cold rolled to interanneal gauge and interannealed at a temperature of at least 400.degree. C. The interannealed strip is cold rolled and further annealed to form the final foil product, having excellent rollability combined with high strength of the final foil.
