The tests in this paper were performed on aluminum AlMgCr alloy (code AA 5052) used in the food industry for making carbonated non-alcoholic drinks cans. The behavior of the alloy has been tested in several well- known and widely consumed carbonated non-alcoholic drinks, such as Coca Cola, Pepsi Cola, Sprite, Fanta, Red Bull and Red Bull - Light. According to their composition, the soft drinks can be divided into three groups: drinks with orthophosphate acid (Coca Cola and Pepsi Cola), drinks with citric acid (Sprite, Fanta) and drinks with caffeine (Red Bull, Red Bull - Light). The corrosion behavior of alloy was investigated using open circuit potential measurements, polarization and electrochemical impedance spectroscopy methods, while the damages on metal surface caused by polarization were confirmed by a light microscope. In the observed soft drinks, the corrosion resistance of AA 5052 alloy increases in sequence: Coca Cola < Pepsi Cola < Red Bull < Red Bull - Light < Sprite < Fanta. Namely, the corrosion current decreases in same order, while the polarization resistance increases. In all carbonated drinks, the corrosion rate of the aluminum alloy can be considered negligible (even 3-4 orders of magnitude smaller than the value allowed in practice). In all cases, no significant damages were seen on the aluminum electrode surface. The corrosion resistance of the AA 5052 alloy is a consequence of the surface layer formation whose properties primarily depend on the chemical composition of the carbonated non-alcoholic drinks. Specifically, impedance measurements conducted at the open circuit potential show that citric acid (present in Sprite and Fanta drinks) and caffeine (present in Red Bull and Red Bull - Light drinks) improve the properties of the surface film (greater resistance and thickness, more compact structure).
