Investigating the Corrosion Performance of EN-AW-8006 Alloy with Mn and Cu Additions

EN-AW-8006 isTwin-Roll Casting a common aluminum alloyAluminum alloys which is used in finstock and container foil applications. Therefore, corrosionCorrosion performance is an important criterion to fulfill the expectations of the service area. Alloying with numerous elements can be carried out to delay the onset of corrosionCorrosion and decrease the corrosion rateCorrosion rate in order to increase the product life and boost sustainabilitySustainability by securing the food stored in the container. In this study, EN-AW-8006 alloyAlloys strips with Mn and Cu additions were produced via Twin-Roll CastingTwin-Roll Casting (TRC) and rolled down to final thickness after homogenizationHomogenization in order to investigate the corrosionCorrosion behavior of the materials. It was concluded that alloying altered the size and distribution of intermetallicsIntermetallics which affected the response of the material against corrosionCorrosion, in return. Increase in the manganese was found to decrease the corrosion rateCorrosion rate, whereas copperCopper increased pitting formationFormation and promoted corrosionCorrosion.
