An Al--Zn--Mg--Cu alloy with improved damage tolerance-strength
combination properties. The present invention relates to an aluminium
alloy product comprising or consisting essentially of, in weight %, about
6.5 to 9.5 zinc (Zn), about 1.2 to 2.2% magnesium (Mg), about 1.0 to 1.9%
copper (Cu), preferable (0.9Mg-0.6).ltoreq.Cu.ltoreq.(0.9Mg+0.05), about
0 to 0.5% zirconium (Zr), about 0 to 0.7% scandium (Sc), about 0 to 0.4%
chromium (Cr), about 0 to 0.3% hafnium (Hf), about 0 to 0.4% titanium
(Ti), about 0 to 0.8% manganese (Mn), the balance being aluminium (Al)
and other incidental elements. The invention relates also to a method of
manufacturing such as alloy.
