The magnesium alloy planking is being used gradually because of its light gravity. But many parameters of forming property of magnesium alloy in shaping can not be found in the special manual. The facts impede seriously the forming engineering to magnesium alloy. In order to get property parameters of this new kind of material in stamping, we designed and manufactured die for experiment and made a series of tests for magnesium alloy planking AZ31 on the GBS-60 the semiautomatic cupping machines. These tests are bulge and hole expansion. Through the experiment, we study the properties of bulge form and holp expansion of magnesium alloy, getting practical valuable data, such as extreme limited bulge coeffictient, average hole expanding date, the temperature affect to forming property and the pattrn of formng force to stroke, and so on. We have cognition on the regularity of the new material in stamping. The results of the experiment above can be used as the reference in stamping technology and design to the magnesium alloy planking.
