PROCESS OF PRODUCING A FOIL OF AN AL-FE-SI TYPE ALUMINIUM ALLOY AND FOIL THEREOF

摘要

The present invention relates to a method of making an aluminum alloy product having a gauge below 200μm. It also relates to an aluminum alloy product having a gauge below the same value and to containers for food packaging application made from the aluminum alloy product. The invention is process of manufacturing an aluminum alloy comprising the following steps: continuous casting an aluminum alloy melt of the following composition, (in weight %): Fe 1.0-1.8, Si 0.3-0.8, Mn up to 0.25, other elements less than or equal to 0.05 each and less than or equal to 0.15 in total, balance aluminum, cold rolling the cast product without an interanneal step to a gauge below 200μm and final annealing the cold rolled product.
