Title (EN) ALUMINUM SHEET WITH ENHANCED FORMABILITY AND AN ALUMINUM CONTAINER MADE FROM ALUMINUM SHEET
(FR) TÔLE D'ALUMINIUM PRÉSENTANT UNE APTITUDE AU FORMAGE AMÉLIORÉE ET RÉCIPIENT D'ALUMINIUM CONSTITUÉ D'UNE TÔLE D'ALUMINIUM
Abstract:
(EN) In some embodiments of the present invention a method includes: obtaining a first aluminum alloy sheet formed from rolling a first ingot of a 3xxx or a 5xxx series aluminum alloy, wherein, prior to rolling, the first ingot has been heated to a sufficient temperature for a sufficient time to achieve a first dispersoid f/r of less than 7.65; and forming a container precursor from the first aluminum alloy sheet, wherein when the first aluminum alloy sheet is formed into the container precursor, the container precursor has less observed surface striations and ridges as compared to a container precursor formed from a second aluminum alloy sheet rolled from a second ingot having a second dispersoid f/r value of 7.65 or greater.
(FR) Selon certains modes de réalisation de la présente invention, un procédé consiste à : obtenir une première tôle d'alliage d'aluminium formée par laminage d'un premier lingot d'un alliage d'aluminium de série 3xxx ou 5xxx, le premier lingot ayant été chauffé, avant le laminage, à une température suffisante pendant une durée suffisante pour obtenir un premier dispersoïde f/r inférieur à 7,65 ; et former un précurseur de récipient à partir de la première tôle d'alliage d'aluminium, la première tôle d'alliage d'aluminium revêtissant la forme du précurseur de récipient, le précurseur de récipient présentant moins de griffures et de stries de surface observées par comparaison avec un précurseur de récipient formé à partir d'une seconde tôle d'alliage d'aluminium laminée à partir d'un second lingot présentant une seconde valeur de dispersoïde f/r supérieure ou égale à 7,65.
