In the present study, warm hydroforming of cell phone cases with magnesium alloy AZ31 sheets was investigated. Fine-grained magnesium alloy sheets were prepared by cross rolling. And the tensile tests were first conducted in order to determine the proper forming temperature. The results showed that the most suitable temperature range appears to be 150-200 degrees C. At last, the magnesium alloy cell phone cases characterized with the small round radius of all edges were formed successfully at 170 degrees C with the low punch velocity and the maximum pressure not less than 5MPa.
