Mechanical and corrosion properties of AA8011 sheets and foils

The mechanical and corrosion properties of a twinroll cast Al-Fe-Si aluminum alloy with 0.74 % Fe and 0.52 % Si (AA8011) were investigated. The influence of the thermo-mechanical processing route on the mechanical behavior of AA8011 sheets was determined. Comparisons were made with AA3003 and Al99.5 sheets. The restoration of the mechanical properties was used in the analysis of the recrystallization behavior of the twin-roll cast AA8011 alloy deformed under cold-working conditions and subsequently annealed. The effect of the cold rolling-annealing combination on the deep drawing properties is presented. The corrosion properties were determined using accelerated corrosion-testing methods and compared to the properties of the Al99.5 sheets.
