Abstract (en)
Al-based alloys intended for deep drawing and/or drawing and exhibiting high mechanical strength characteristics as well as good isotropy (low distortion wedge content) and good cold processability. The alloys according to the invention have the following compositions by weight (%): (I) (II) Fe </= 0.25 from 0.7 to 1.5 Si </= 0.25 </= 0.4 Mn from 0.8 to 1.6 </= 0.8 Mg from 0.7 to 2.5 from 1.5 to 3 Cu from 0 to 0.6 from 0 to 0.6 Cr from 0 to 0.35 from 0 to 0.35 Ti from 0 to 0.1 from 0 to 0.1 V from 0 to 0.1 from 0 to 0.1 Remainder Al and unavoidable remainder Al and unavoiable impurities: impurities Each </= 0.05% </= 0.05 Total </= 0.15% </= 0.15 They are particularly well-suited for the manufacture of drawn cans, particularly beverage cans, which are lighter and/or stronger with an increased saving of material, the manufacturing range being wholly comparable with that of the conventional alloys (3004/3104), with optional omission of the intermediate annealing operations.
Abstract (fr)
L'invention concerne des alliages à base d'A1 destinés à l'emboutissage et/ou à l'étirage et présentant des caractéristiques mécaniques de résistance élevées ainsi qu'une bonne isotropie (faible taux de cornes) et une bonne formabilité à froid. Les alliages selon l'invention possèdent les compositions pondérales suivantes (%) : <IMAGE> Ils sont particulièrement bien adaptés pour la fabrication de boîtes étirées, particulièrement de boîtes-boissons, plus légères et/ou plus résistantes avec une économie de matière accrue, la gamme de fabrication étant tout à fait comparable à celle des alliages classiques (3004/3104), avec omission éventuelle des recuits intermédiaires. <IMAGE>
