Texture and conical cup value (C. C. V.) of 1050 aluminum sheets were investigated. Secondary cold cross rolling was applied in order to weaken the cube texture which has been known to be unfavorable for metal sheet formability. Primarily straight-rolled sheets were subjected to secondary cross rolling successively along the transverse direction to primary rolling. Experimentally remodelled reversing cross rolling mill from common type of a two-high mill was used to perform the secondary cross rolling. 5-15% secondary cross rolling was exerted to develope the rolled texture composed of preferred orientation {034}<986>. Resulting recrystallized texture obtained from it secondarily cross-rolled included several preferred orientations {034}<986>, {5 10 31}<5 44 15> and {053}<135>, instead of cube orientation. Consequently, weakening the cube texture by means of secondary cross rolling was capable of improving the C. C. V. and reducing plastic anisotropy of the sheets.
