The scheme for thermomechanical treatment of 2519 aluminum alloy is designed by orthogonal test, the heat treatment experiments are made and the mechanical properties and electrochemical corrosion resistance are tested according to the scheme. Influence of each factor on mechanical properties of 2519 alloy is analyzed. The results show that the tensile strength of 2519 alloy can be improved obviously, but its electrochemical corrosion resistance decreases to some extent through thermomechanical treatment. The optimum conditions of thermomechanical treatment of 2519 alloy are as follows: an aquenching temperature of 530 ℃, a solid solution time of 0.5 h, a deformability ratio of 15%, an aging temperature of 150 ℃, and a soak time of 10 h.
