Generally, it is essential to improve the performance of the propulsion engine as well as the weight of the structure, in order to increase the output and speed of the vehicle such as automobiles and trains. It was manufactured by adopting aluminum alloy as the candidate alloy of lightweight alloy to be used for interior and exterior materials of high-speed train. The development of more reliable lightweight aluminum and aluminum alloy for interior or exterior materials has been the scope of this study. The characteristics of the casting material showed the mechanical characteristics that are not inferior to those of the foreign materials. The hardness, microstructure and tensile properties of the 6063, 6N01, 6061, 6060, 6005 and 5083 aluminum alloys selected as present study by literature research were similar to those of external materials (made by Alcan, Canada).
