For improvement the processing and gaining uniformity texture structure and performance the thickness direction of direct chill cast DCAA 5052 aluminum alloy band after first hot rolling with different reduction, the material was annealed at 454 ℃ and then cold rolling with different reduction, we test and examined the texture at surface, quarter and center layer of the sample by use X-ray diffraction method, we calculated the data by use special software and analyses the difference texture at surface, quarter and center layer. The intension gradient of β texture was along the direction from surface to center layer gradually enhance at different reduction sample. For β texture, the intension gradient was along the direction from surface to center layer gradually reduce, the volume fraction gradually augment and the intensity gradually were almost equal with the cold rolling reduction increased from 0% to 90%.
