Aluminum alloys present higher formability under electromagnetic forming,so this opens up a broad application prospect for electromagnetic forming in auto industries.In this paper,according to the trait of electromagnetic tube bulging,research on the forming limits of electromagnetic tube bulging is carried out,the forming limit diagram of 1060 aluminum and 3A21 aluminum alloy are built,and the effect of size on the formability of ring is also considered.
