The invention discloses a process for producing a thin-walled aluminum alloy tube material. The process comprises the steps of composition optimization, casting for blank preparation, extrusion molding, quenching, stretching and straightening and aging treatment; after composition optimization, the alloy comprises the following composition: 0.55-0.65 wt% of Si, 0.32-0.38 wt% of Fe, 0.17-0.25 wt% of Cu, 0.09-0.11 wt% of Mn, 0.88-0.98 wt% of Mg, 0.06-0.15 wt% of Cr, 0.09-0.11 wt% of Zn, 0.09-0.11 wt% of Ti, and the balance being Al; the quenching step is carried out by two steps, the first step is to adopt high pressure water mist quenching, and the second step is to adopt a water cooling mode to quench. The aluminum alloy tube material produced by the process has small size deviation, and has excellent comprehensive mechanical properties, wherein the yield strength is not less than 270 MPa, the tensile strength is not less than 340 MPa, and the elongation rate after fracture is not less than 10%.
