Aluminium alloy for the production of semi-finished products or components for motor vehicles, method for producing an aluminium alloy strip from this aluminium alloy and aluminium alloy strip and uses thereof

摘要

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.
