Abstract. The Al-Zn-Mg-Cu aluminum alloys are primarily used in the aerospace industry as
structural components. This study aim to improve properties of Al-5.6% Zn-2.5%Mg-1.6%Cu such
as impact toughness, thermal stability and corrosion resistance by using quenching in 30%
polyethylene glycol and addition 0.1%Zr to this alloy. Results showed that the addition 0.1% Zr to
base alloy improve impact toughness by (40%) when quenching in water, and by (60 %) when
quenching in 30%PAG corresponding to the base alloy when aging at 150 ?C. Also results showed
that the thermal stability improved when we addition 0.1% Zr by (20%). An improvement of
corrosion resistance when addition 0.1% Zr (B alloy) by (326 %), at aging time 150?C in
comparison to the base alloy.
