Abstract:
An aluminum alloy wrought product including, in wt. %, Mg 3.0 to 7.0, Zn 0.6 to 2.8, Mn 0 to 1.0, Cu 0 to 2.0, Sc 0 to 0.6, at least one element selected from the group of Zr 0.04 to 0.4, Cr 0.04 to 0.4, Hf 0.04 to 0.4 and Ti 0.01 to 0.3; Fe maximum 0.3, Si maximum 0.3, inevitable impurities, and balance aluminum. The range for the Zn-content in wt. % is a function of the Mg-content according to: lower-limit of the Zn-range: [Zn]=0.34[Mg]−0.4, and upper-limit of the Zn-range: [Zn]=0.34[Mg]+0.4.
