Abstract: The invention relates to a method for re-melting coated aluminum alloy scrap comprising a step of supplying shredded coated aluminum alloy scrap, consisting of individual entities; a decoating step, a step of preparing a heel, a step of loading and melting the decoated scrap on the heel. The invention is characterized in that the scrap has a specific geometry wherein at least 50% of the individual entities of the shredded coated scrap has a fold ratio (R) of less than or equal to 0.6, wherein the fold ratio (R) of an individual entity is defined by: fold ratio=R=(unfolded area−folded area)/(unfolded area), wherein the folded area is the maximum area of the orthogonal projection of the individual entity onto a plane and the unfolded area is the total area of the same individual entity after it has been unfolded.
