Abstract (en)
[origin: WO2005001149A2] The invention relates to a drawn, laminated or forged aluminium alloy product, characterised in comprising (in mass %): Zn 6.7 7.5 %, Cu 2.0 2.8 %, Mg 1.6 2.2 one or several elements selected from the group Zr 0.08 0.20 % ,Cr 0.05 0.25 %, Sc 0.01 0.50%, Hf 0.05 0.20 %, V 0.02 0.20%, Fe +Si < 0.20%, other elements = 0.05 % each and = 0.15 % in total, the residue being aluminium. Said product has an improved compromise between static mechanical resistance and tolerance to damage.
