Abstract: High-purity aluminum foils were obtained by cross shear cold rolling with different parameters, and the effects of rolling parameters on the as-rolled textures in aluminum foils were investigated. Compared with the symmetrically rolled aluminum foils, six kinds of textures were found in cross shear rolled foils whose volume fraction and distribution are different from the former because of the effect of cross shear area. On the whole, the content of textures formed on the slow roller side is higher than that on the fast roller side. Both the S{123}<634> and C{112}<111> textures have the same evolution trends, as well as both the {001}<100> cube texture and the {001}<110> rotated cube texture. The content of Goss texture is lower and insensitive to either the fast or slow roller, the reduction and the speed ratio, while the volume fraction of texture is sensitive to the speed ratio and the content of cold rolled texture can be increased through adjusting the speed ratio and reduction on the final pass. It was found that the content of cold-rolled textures which is higher than that by symmetric rolling can be obtained if the speed ratio is 1.06 or 1.13.
