Abstract
The invention is an aluminum alloy strip having the composition Si: 1.00-1.50% %, Fe: <=0.30%, Mn: <=0.30%, Mg: 0.20%-0.44%, Cu: 0.80%-1.50%, Ti: 0.03%-0.15%, Cr: <=0.10%, Zn: <−0.10%. This strip has formability properties equivalent to that of an AA5182 alloy strip in state 0. This invention further relates to the production of motor vehicle doors, the inner panel of which is made with the strip according to the invention.
