Abstract (en)
[origin: EP2770071A1] An aluminum alloy comprises 0.8 wt.% or less iron, 0.5 wt.% or less silicon, 0.9-1.5 wt.% manganese, 0.25 wt.% or less magnesium, 0.125 wt.% or less copper, 0.05 wt.% or less chromium, 0.05 wt.% or less titanium, 0.05 wt.% or less titanium, 0.05 wt.% or less zirconium, and remainder of aluminum and unavoidable elements at less than 0.05 wt.% individually and less than 0.15 wt.% in total. The total content of magnesium and copper is 0.15-0.25 wt.%. The proportion of magnesium in the aluminum alloy is more than the proportion of copper in the aluminum alloy. Independent claims are included for the following: (1) preparation of aluminum alloy strip; and (2) aluminum alloy strip.
