Abstract: The paper deals with the effects of thermo-mechanical processing parameters on the properties of two Al-Fe-Si foil alloys. Two twin roll cast alloys with high Fe/Si ratios (Fe/Si≈6) were processed under different combinations of homogenization, deformation and annealing treatments. The influence of small additions of manganese on the mechanical behavior and plastic anisotropy of sheets in hardening and annealing conditions are described. The corrosion resistance of tested sheets in chloride ambience is also presented, because this type of Al foils is dominantly used in the packaging (food) industry and heat exchangers.

Abstract: This paper describes the general trends correlating mechanical and corrosion properties with chemical composition of some Al-Fe-Si and Al-Fe-Mn-Si alloys for foils. These Al-rich eutectic alloys based on Al-Fe-Si and Al-Fe-Mn, when roll cast and appropriately processed to give fine and regular dispersion of intemetallic particles, can provide good combinations of strength and ductility. These characteristics have been responsible for the alloy success in replacing commercially pure (CP) aluminum for applications in thin sheet and foil gauges. The objective was to obtain an opinion about the possible role of alloying elements in corrosion behavior and mechanical properties of these commercial materials produced by cold rolling of twin roll cast strips.
