Al has very good corrosion resistance and corrosion properties. The corrosion resistance of Al-cast alloys is different because these alloys contain a lot of elements, especially in secondary alloys, which contain more impurity elements, of which Fe is the most common. This study deals with secondary AlSi7Mg0.3 cast alloys, which contain more Fe and are affected by a chloride corrosive environment. This environment was selected based on the application of castings in the automotive industry. The main object was to research the effect of such an environment on basic mechanical properties and fatigue properties. The results show that a higher Fe content does not lead to a significant reduction in the properties of the casting, and the chloride environment is not so harmful. Therefore, it can be stated that the investigated secondary sand-cast experimental materials can replace primary alloys without losing the required corrosion and mechanical properties.
