AluminiumAluminium extrusionsExtrusion are now being produced with higher recycled content across the automotiveAutomotive sector, driven by the manufacturers desire to reduce the carbonCarbon footprint of their vehicles. Increasing recycled content can increase the levels of many alloying elements including Fe, Cu, Zn, Mn, etc. and these present challenges that can affect not just the mechanical propertiesMechanical properties of the alloys, but also downstream processingProcessing operations such as joining and surface finishing. This review will analyze the available published literature and investigate how the impurities from recycled feedstock can influence the extrudability, mechanical propertiesMechanical properties, and surface qualityQuality of the final product. It will address the impact of these changes on forming, bending, and surface treatments such as anodizing and painting.
