Abstract Scope 6000 series alloys are widely used in automotive applications due to their good formability, strength, and corrosion resistance. Nevertheless, intergranular corrosion (IGC) can occur due to the formation of corrosion-active Mg2Si-phases or copper-enriched grain boundary nanofilms. The formation of those films highly depends on the alloy composition and thermomechanical history. The present study explores the underlying mechanism of IGC of different industrially-used extruded, rolled and cast 6000 aluminum alloys with high copper contents using standardized immersion tests (DIN ISO 11846 B). A particular focus is set on the influence of processing parameters on grain size and morphology and its effect on the corrosion susceptibility. The results are correlated to the microstructure using optical light microscopy, scanning and transmission electron microscopy as well as differential scanning calorimetry. The corrosion susceptibility as well as the corrosion mechanism was found to be highly dependent on the processing route and the resulting grain structure.
