Abstract (en)

[origin: WO03074747A1] The invention relates to an aluminium alloy sheet or strip with a thickness of between 1 and 5 mm which is intended for the production of stamped and bent parts having a small bend radius, the composition ( % by weight) of said alloy comprising: Si<0.4, Fe<0.4, Cu<0.4, Mn + Cr:0.3-0.7, Mg:4-5.5, Zn<1, other elements <0.05 each and <0.15 in total, and the remainder aluminium. Moreover, the inventive sheet or strip presents the following properties: an elastic limit R0.2 in direction T>215 MPa, elongation A80>15 % and a difference Rm - R0,2 >80 MPa. Said sheets and strips are used, for example, for the production of parts for motor vehicles, such as reinforcements for openable panels or jacks.
