After extrusion, cold rolling and T-6 treatment, microstructure, texture development, and deep drawability of Al-5.09%Zn-1.83%Mg-0.32%Cu-0.25%Mn-alloy with 0.1% Sc are studied. After T-6 treatment, recrystallized equiaxed grains with an average grain size of 1 similar to 2 square are obtained. During extrusion the very strong < 111 >-fiber + medium sharp < 100 >-fiber + weak < 210 >-fiber texture is developed, which influences the formation of rolling texture. The texture, after 80% cold rolling, can be described by the strong (112)< 111 >(Cu) + {123}< 634 >(S) component in the cross section of the extruded rod, the strong beta-fiber + weak {110}< 001 >(Goss) components in the longitudinal section, andthestrong {1101 < 112 >(Bs) +weak {001}< 100 >(Cube) components in the transverse section, The types of rolling texture are not changed after the T-6 treatment, but the maximum density of ODF is higher. The calculated mean r-values, r., and the planar anisotropy, Ar, are relatively high, which are dependent on the texture.
