Beschreibung
Zusammenfassung:	The invention concerns a 5xxx series aluminium sheet made of an alloy comprising in wt. %: Mg: 2.5-4.0, Mn: 0.7-1.2, Fe: 0.25-0.55, Si: 0.20-0.50, Cu: 0.10-0.25, Cr: up to 0.1, Zn: up to 0.25, Ti: up to 0.1, rest aluminium and unavoidable impurities up to 0.05 each and up to 0.15 in total. The method for producing the 5xxx series aluminium sheet of the invention comprises the steps of casting an ingot with a composition according to the invention, pre-heating the ingot, rough hot rolling on a reversible mill with a rough hot rolling entry temperature of more than 440° C., finish hot rolling the ingot with a hot rolling exit temperature of at least 300° C., cold rolling to obtain a cold rolled sheet. The invention also concerns a can end and a beverage can.
