Corrosion of aluminum cans is a problem of great economic, environmental and security relevance in the beverage industry and occurs during storage, handling and transport. However, there are few studies that assess its development and its causes. It occurs mainly in packaging that contains products with aggressive characteristics, such as acidic beverages. Thus, this study evaluated the in situ corrosion of aluminum cans that had contact with acidic solutions containing only chloride, copper or a mixture of these ions, in addition to cans taken in market containing carbonated drink, evaluating the influence of these variables, and using optical microscopy and scanning electron microscopy. The most severe cases of attack were observed in specimens from contact with the solution containing both ions (Cl + Cu) and was also observed occurrence of corrosion on samples that had contact with solutions containing only one of the ions. Most of the pits had wide/shallow conformation as classification of G46-94 standard (ASTM, 2013), observed in the evaluation of the cross section. It was possible to observe corrosion in all market samples, with the presence of ions that are part of the beverages ingredients, indicating its influence on the corrosion process.
