Abstract: The article presents the results of a potentiostatic study of aluminum alloy АlMg5.5Li2.1Zr0.15 of the duralumin type with indium in NaCl solutions with concentrations of 0.03%, 0.3% and 3.0% by weight, at a potential expansion rate of 2 mV/s. The addition of indium to aluminum alloy АlMg5.5Li2.1Zr0.15 of the duralumin type was 0.01-1.0% by weight. It was shown that indium alloying of this alloy reduces its corrosion rate by 13-18%, which is accompanied by a shift to the range of positive values of electrochemical potentials. An increase in the NaCl concentration in solution increases the corrosion rate of alloys, regardless of their composition, and shifts electrochemical potentials in the negative direction of the ordinate axis
