Abstract: Taking Cu-Al-Zn alloy as the research object, the microstructure of copper alloy was adjusted by combining rolling and short-time annealing process, which solved the problem of high strength but poor ductility of copper alloy after rolling deformation, and achieved the purpose of synergistically improving the comprehensive mechanical properties. The microstructure and mechanical properties of rolled Cu-Al-Zn alloy after annealing were comprehensively analyzed by metallographic examination, mechanical tests, Bauschinger effect tests, Digital Image Correlation analysis（DIC）. The results show that the Cu-Al-Zn alloy is rolled at different temperatures, and it is found that the samples obtained by annealing at 325℃ for 20 minutes after rolling at room temperature show an optimal matching relationship between strength and ductility, with a tensile strength of 581MPa and a uniform elongation of 20.5%.
