Based on the ABAQUS/explicit finite element method, the deep drawing of 6A16 alloy pre-aged and then storaged at room temperature for 1 week with various blank-holder forces (10, 14, 18 kN) was studied. The distribution and variation of stress and strain in deformation zones were investigated to drive the forming property and process of the alloy. Besides, the simulation result was verified combined with the deep drawing experiments. The results show that the stress and strain of the deformation zone have an incremental trend with the blank-holder force increasing while the deformation degree and grain size within a certain deformation zone have an obvious increase and an enlargement, respectively. After the deep drawing, the hardness of products also increases with the enhancement of blank-holder force. The blank-holder force of 18 kN is certified as the preferential one by the analysis of microstructure and simulation results.
