Aluminum and its alloys have prompted significant development in several industrial fields. However, aluminum is typically very difficult to weld and sometimes generates undesirable formations during various processes. Therefore, the properties of aluminum must be thoroughly investigated to improve its applicability to various engineering problems. In this study, Al-xMg alloys with x=0, 2, and 4wt% were successfully formed using a hot extrusion method and characterized using various electrochemical and surface analysis techniques following immersion in a 0.1M Na2SO4+0.01M NaCl solution. The results indicate that an increase in Mg content in Al-based alloys leads to better pitting resistance. This could be a result of significant changes in grain size and passive film formation on alloy surfaces, which lead to superior physical properties.
