Summary: | This invention describes a method of producing a flat aluminum sheet product (2) by providing an aluminum alloy stock, hot working the aluminum alloy stock through preheating and hot rolling, side sawing the aluminum alloy stock, subjecting the aluminum alloy stock to solution heat treatment, cold rolling the aluminum alloy stock to reduce its thickness by about 0.25% to about 5%, and finally stretching the aluminum alloy stock.
La présente invention concerne un procédé de production d'une tôle d'aluminium plate (2) via la fourniture d'un stock d'alliage d'aluminium, d'un travail à chaud de ce stock d'alliage d'aluminium par un préchauffage et un laminage à chaud, un sciage latéral du stock d'alliage d'aluminium, la soumission de ce stock d'alliage d'aluminium à un thermotraitement en solution, un laminage à froid de ce stock d'alliage d'aluminium de façon à réduire son épaisseur d'environ 0,25 % à environ 5 % et finalement, l'étirage de ce stock d'alliage d'aluminium. |
