Abstract: The present invention relates to an aluminum alloy product for use as a finstock material within brazed heat exchangers and, more particularly, to a finstock material having high strength and conductivity after brazing. The invention is an aluminum alloy finstock comprising the following composition in weight %: Fe 0.8-1.25; Si 0.8-1.25; Mn0.70-1.50; Cu0.05-0.50; Znup to 2.5; other elements less than or equal to 0.05 each and less than or equal to 0.15 in total; and balance aluminum. The invention also relates to a method of making the finstock material.
