The Al-Mg alloy system has received considerable attention as an alternative to steel to decrease structural weights and increase overall fuel efficiency due to their high strength to weight ratio and weldability. Cold rolling is an important process of wide aluminum alloy sheets. Rolling reduction and the following annealing temperature are two important parameters during the rolling process. In the present study, effects of rolling conditions on microstructure and mechanical properties of Al-Mg based alloys. The melt was held at 780 ℃ for 20 min and poured into a mold. And as-cast Al-Mg alloys were hot-extruded into a plate with 4 mm in thickness. The extruded plates were cold rolled into a sheet with 0.2mm in thickness. After rolling, sheets were annealed with different temperature. Microstructures were obtained using SEM, EBSD and X-ray diffractometer. Tensile tests were performed using a universal material test machine at room temperature.
