To meet the requirement of the high shape, dimensional accuracy and mechanical properties of the 6061 aluminum alloy thin-walled tubular part, the different heat treatments, such as the anneal,solution,incomplete annealing and half solution, of the 6061 aluminum alloy hot extrusion tubes before spinning were analyzed. The influence of the heat treatment on the spinning process and the mechanical properties of the spun part were obtained. The results show that for the 6061 aluminum alloy hot extrusion tube, the spinning process proceeds smoothly and the tensile mechanical property of spun part is no less than 245 MPa through the half solution heat treatment (heating to 460℃, insulation 30 min, water-cooling)before spinning.
