  • ALUMINIUM FOIL ALLOY
    Publication number: 20110165015
    Abstract: The present invention relates to a method of making an aluminium alloy product having a gauge below 200 ?m. It also relates to an aluminium alloy product having a gauge below the same value and to containers for food packaging applications made from the aluminium alloy product. The invention is a process of manufacturing an aluminium alloy comprising the following steps: continuous casting an aluminium 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 aluminium, cold rolling the cast product without an interanneal step to a gauge below 200 ?m and final annealing the cold rolled product.

  • Process for manufacturing a strip of aluminium alloy for lithographic printing plates
    Patent number: 6655282
    Abstract: A process for manufacturing a strip of aluminium or an aluminium alloy for electrolytically roughened lithographic printing plates, in which the alloy is continuously cast as a strip and then rolled to final thickness, is such that the cast strip is rolled to final thickness with a thickness reduction of at least 90% without any further heating. The resultant microstructure in the region close to the surface of the strip leads to improved electrolytic etching behaviour.
