The 5A02 aluminum alloy thin-wall pipe was rolled using a three-roller precision tube mill. Optical microscope, hardness testing machine and universal testing machine were used to investigate the microstructure and properties of the 5A02 aluminum alloy pipe rolled with different processing rates and annealing with different temperatures and holding time. The 5A02 aluminum alloy was firstly rolled with a strain of 57.2%, then it was annealed at 380-410 ℃ for 30-60 min, which was finally determined as the reasonable rolling process. After rolling process, the finished pipe was annealed at 410 ℃ for 60 min. The microstructure of the pipe is composed of fine recrystallized grains with all fibrous structure completely disappeared, the mechanical properties of which is satisfied with the application requirements.
