Summary:An aluminium alloy suitable for processing into a lithographic sheet, the alloy having a composition in wt.% unless otherwise stated of Mg 0.03 - 0.15 Mn 0.03 - 0.07 Si less than or equal to 0.13 Fe less than or equal to 0.4 Ti up to 300ppm (free titanium), the balance being Al and incidental impurities. L'invention porte sur un alliage d'aluminium pour feuilles de lithographie dont la composition en % en poids est, sauf stipulation différente, de: Mg de 0,03 à 0,15; Mn de 0,03 à 0,07; Si inférieur ou égal à 0,13; Fe inférieur ou égal à 0,4; Ti jusqu'à 300 ppm (titane libre), et le reliquat d'Al et d'impuretés éventuelles.
