| Abstract Scope |
Aluminium extrusions are now being produced with higher recycled content across the automotive sector, driven by the manufacturers desire to reduce the carbon footprint of their vehicles. Increasing recycled content increases the levels of many alloying elements including Fe, Cu, Zn, Mn etc and these present challenges that can affect not just the mechanical properties of the alloys, but also downstream processing 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 properties and surface quality of the final product. It will address the impact of these changes on forming, machining, joining and surface treatments such as anodizing and painting. The review will also consider advancements in alloy design, alloy blending techniques and post-extrusion treatments that may mitigate some of the detrimental effects that come from deviating from the standard alloy compositions. |
