The invention concerns a method for producing a 6xxx series aluminium sheet comprising the steps of homogenizing an ingot made from a 6XXX series aluminum alloy; cooling the homogenized ingot with a cooling rate in a range of from 150&#xb0; C./h to 2000&#xb0; C./h directly to the hot rolling starting temperature; hot rolling the ingot to a hot rolling final thickness and coiling at the hot rolling final thickness with such conditions that at least 50% recrystallization is obtained; cold rolling to obtain a cold rolled sheet. The method of the invention is particularly helpful to make sheets for the automotive industry which combine high tensile yield strength and good formability properties suitable for cold stamping operations, as well as high surface quality and high corrosion resistance with a high productivity.

Method of making 6XXX aluminium sheets

A method of manufacturing an aluminum alloy ingot using scrap aluminum alloy in the 2xxx or 7xxx series, and a fabrication method after rolling, extrusion and/or forging of an aeronautical structure comprising the steps in the above method, and then at least one rolling, extrusion and/or forging step of the aluminum alloy ingot in the series of scrap used.

Method for recycling scrap of 2xxx or 7xxx series alloy
