The high-purity aluminum with a purity of 5N5 was cold-rolled with a cumulative deformation of 70%, and the deformed high-purity aluminum was annealed at different temperatures and time. The microstructure and mechanical properties of deformed high purity aluminum and heat treatment were studied by means of microstructure analysis and mechanical property test.The results show that, after the cold deformation of 70% 5N5 aluminum alloy, the work hardening is obvious, the tensile strength and microhardness are improved greatly, and the change trend after annealing is consistent, all with the increase of annealing temperature and the increase of holding time are gradually reduced. After annealing at 330 × 20min, the microhardness decreased sharply, and the uniform fine equiaxed grains appeared, the occurrence of a complete recrystallization, more than the best annealing temperature and time after recrystallization, continue to increase the annealing temperature or increase the holding time will make recrystallized grains grow up, increasing the temperature high or increase the longer the insulation time, the more obvious the phenomenon of grain growth.
