Due to global regulations on fuel consumption and emissions, automakers and related industries are increasingly interested in the application of lightweight materials to increase the efficiency and to reduce weight of automobiles. In particular, in the case of an aluminum alloy, which is a representative material of light metals, many researches are being actively carried out to overcome the limit of lightweighting by applying the high strength alloys. However, due to the low extrudability of high strength aluminum alloy, it is difficult to apply to automobile parts. In this study, we investigated the improvement of extrudability by controlling the content of alloy elements in A7075 aluminum alloy. As a result, we have successfully developed a high extrudable A7075 alloy having with average yield strength of 560 MPa, tensile strength of 600 MPa, and elongation of 13%.
