Background: Corrosion is a decrease in the quality of a material or metal to electrolyte reactions in the environment that affect the life of the material. Corrosion processes occur in acidic environments, sea water, rainwater, and soil are the result of chemical reactions that are also caused by electrochemical processes. The purpose of this study was to determine the corrosion resistance of aluminum metal to variations in 0.1 M and 0.5 M Hydrochloric Acid solution. This research uses an aluminum plate that will be immersed for 5 days with 0.1 M HCl and 0.5 M HCl solution. Methods: The method of data collection is by scanning Scanning Electron Microscopy (SEM) on each aluminum plate specimen that has been given corrosion treatment by heating at a temperature of 60 C HCl solution is one of the factors causing corrosion of metals. Finding: If in the free environment, air, temperature, and acidic substances are most commonly found as a factor causing corrosion. The increased corrosion rate is due to the higher concentration of the cause of corrosion. Conclusion: In this discussion, HCl as a concentration is used, and aluminum as a metal is tested.
