Abstract
The effects of Mg and Cu amounts on the casting characteristics and tensile property of Al-Zn-Mg-Cu alloys were investigated for the development of high strength aluminium alloys for gravity mold casting. Increase of copper amounts in Al-6%Zn-3%Mgy% Cu alloys resulted in reduction of the fluidity of these alloys and had little effects on the tensile property of these alloys. Increase of magnesium amounts from 1.0wt% to 3.3wt% in Al-6%Zn-x%Mg-0.5%Cu alloys resulted in reduction of the elongation of these alloys from 12% to 3% and increase of the tensile strength of these alloys from 340MPa to 450MPa, but had little effects on the fluidity of these alloys.
