AB Aluminium alloys are, due to their properties, an important part of all shaped castings made especially for the aerospace and automotive industry. One of the widely used alloys, for the production of castings in the automotive industry, is the AlSi7Mg0.3 alloy. In the experiment, which is the content of this paper, two castings from AlSi7Mg0.3 alloy were tested. Iron is a common contaminant in aluminium alloys and its content in the alloy is increased by the use of secondary aluminium alloys or by various causes during the production process itself. In the experiment, the corrosion resistance of castings was evaluated (in one of them the increased Fe content) under the specified conditions in the corrosion chamber with salt mist. Corrosion properties were evaluated using confocal laser microscopy. Based on the results of the microscopic analysis, the relevant conclusions were formulated. From the experiment, it is evident that the increased iron content (0.319 [wt. %]) does not, in this case, affect the corrosion resistance of casting.
