Beschreibung
Zusammenfassung:	A method for manufacturing a rolled product for automobile bodywork or body structure with an alloy containing Si: 0.75 -1.10, Fe: max 0.4, Cu: 0.5 - 0.8, Mn: 0.1 - 0.4, Mg: 0.75 - 1, Ti: max 0.15, Cr: max 0.1 and V: max 0.1 is disclosed with several process steps from casting the ingot to forming and painting a car body part. The various possibilities of pre ageing of the sheet as well as of the heat treatment of the part offer advantageous material properties in forming, material strength and low sensitivity to the bake hardening process which can vary depending in the part location in the car body.
