Magnesium alloys can be used for reducing the weight of various structural products. They have attracted considerable attention as materials with a reduced environmental load, since they help to save both resources and energy. In order to use Mg alloys for manufacturing vehicles, it is important to investigate the tensile properties, thermal stability and formability. The tensile properties and formability of high strength of Mg alloy and 6N01 aluminum alloy was examined. High strength in A6N01 alloy rolled sheet decreases monotonically annealing temperature rise to the static recrystallization temperature, but in the flame retardant Mg alloy without significantly reduced for compounds to suppress the grain growth of Ma phase, flame retardant Mg alloy was maintained high strength between 200 and 400℃. In flame resistance Mg alloy, an examination of the drawability revealed that drawing of the alloy at 100℃ and room temperature was not possible, and the conical cup value (CCV) was higher than that of the AZ31 magnesium alloy. However, the drawability improved remarkably for tests at 150 to 250℃, with corresponding good CCVs.
