Abstract. This paper aims to study the secondary aluminium alloy AlSi7Mg0.3 with higher Fe content after heat treatment. The addition of Mn is also investigated. The quantitative analysis was performed to evaluate the effect of higher Fe content on the amount and shape of platelet-like Fe-rich intermetallic phases. As a method of corrosion resistance testing an immersion test in 3.5% NaCl was used. This test was done in order to evaluate the influence of higher Fe content and Mn addition in heat-treated AlSi7Mg0.3 alloys. The results show that the Mn addition increases the corrosion resistance of AlSi7Mg0.3 alloys, but not significantly. AlSi7Mg0.3 alloys have numerous uses within the automobile and other sectors.
