Magnesium alloys, the lightest metal structure material for engineering applications, have taken a great interest in the automotive, aerospace, weapons, electronic and other fields, because of their low density, high specific strength and stiffness, good damping characteristics, as well as excellent castability. Especially in the field of automobile industry, magnesium alloys have replaced the steel, cast iron and even aluminum alloys (Magnesium is the lightest of all structural metals), because they can reduce the weight of vehicles, so that significantly contribute to fuel economy and reducing CO2 emissions. Nowadays, magnesium alloy productshave been mainly manufactured by the die casting process. Both Magnesium Sheets\Plates AZ31 alloy and Magnesium Round bars AZ31 alloy are the most ductile and the most popular amongst AZ wrought alloys. Soft as it is, this alloy offers good combination of strength and ductility for structural application after deformation with severe reductions.
