The drawing process for the manufacture of an aluminum alloy liner has been very little studied, perhaps due to the low tonnage processed by this method, which makes it low relevant to other processes of plastic deformation. Nevertheless, it is an economically competitive method for the manufacture of light pressure vessels, consisting of a liner of aluminum alloy reinforced with fiber glass. The effects over the microstructure of an aluminum alloy AA 6061 during the spinning process are little known. Nevertheless, the changes can favor the microcracking of the alloy during the process of plastic deformation. In this work, the microstructural changes produced by the plastic deformation during the spinning process and the final heat treatment of an aluminum liner and the effects of the processing variables are studied
