Effect of Increasing Fe Content on the Fatigue Resistance of Secondary Aluminium Alloy AlSi7Mg0.6

Abstract

Since the discovery of aluminium, scientists have always seen aluminium alloys as excellent construction materials. They are among the most widely used metals in many industries. Over the last decades, secondary aluminium alloys have received much attention. Recycling aluminium scrap is beneficial for the environment. Furthermore, it requires less energy, so the production costs are lower compared to primary aluminium. The most common obstacle while using secondary aluminium alloys is their increased iron content because it negatively affects their properties. The study aims to widen current knowledge of iron's impact on the fatigue resistance of secondary aluminium alloys.
