Abstract
A method is described for making an aluminum alloy foil suitable for application to fins used in heat exchangers. The method comprises providing an aluminum alloy composition containing about 0.27% to about 0.55% by weight of iron, about 0.06% to about 0.55% by weight of silicon and optionally up to about 0.20% by weight of copper; continuously casting a coiled strip from the molten aluminum alloy; cold rolling the continuously cast coil to a final gauge of about 0.076 mm to about 0.152 mm and partially annealing the aluminum alloy sheet at a temperature below about 260° C., with a maximum overheat of about 10° C. to anneal the aluminum alloy foil substantially without any recrystallization.
