Title (EN) AL-MG ALLOY SHEET OR STRIP FOR THE PRODUCTION OF BENT PARTS HAVING A SMALL BEND RADIUS
(FR) TOLE OU BA 0NDE EN ALLIAGE AL-MG POUR LA FABRICATION DE PIECES PLIEES A FAIBLE RAYON DE PLIAGE
Abstract: front page image
(EN)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.
(FR)L'invention a pour objet une tôle ou bande en alliage d'aluminium d'épaisseur comprise entre 1 et 5 mm, destinée à la fabrication de pièces embouties et pliées à faible rayon de pliage, de composition (% en poids): Si<0,4, Fe<0,4 Cu<0 Mn +Cr:0,3-07 Mg:4,0-5,5 Zn<1 autres élements <0,05 chacun et <0,15 au total, reste aluminium, présentant une limite d'élasticité R0,2 sens T>215 Mpa, un allongement A80> % et une différence Rm - R0,2 >Mpa. Les tôles et bandes selon l'invention sont utilisées notamment pour la fabrication de pièces pour l'automobile telles que le renfort d'ouvrants ou des crics..
