    Abstract: 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.

    Abstract: The invention relates to a beverage can on the basis of an aluminum alloy, preferably for a carbonated drink, comprising: a body (6) having a cylindrical shape and an outer diameter D1; a concave dome-shaped bottom (1) having a depth H1 at its center, an outer diameter D3 and a rectilinear part (2) having a height H3; a convex lower ring (7) having a stand diameter D2 and a flat surface with a width L2; an outer shoulder (5) of radius R1; a shime (4) connecting the outer shoulder (5) and the lower ring (7). The invention is characterized in that the thickness of the sheet of the dome is from 180 to 230 μm, preferably from 190 to 220 μm; and in that the outer diameter D3 of the concave dome (1) is from 36 to 44 mm, preferably from 37 to 43 mm; and in that the width of the lower ring L4 is from 3 to 4.5 mm, preferably from 3.3 to 4 mm; and in that the lower ring has concave deformations (8) which are distributed at regular intervals along the lower ring (7).
