The paper analyzes properties of the 8176 aluminum alloy. The alloy was studied for corrosion resistance in such media as sodium hydroxide (NaOH), calcium hydroxide (Ca(OH)2), sodium chloride (NaCl), SZhR-3 oil and in the high humidity (H2O) conditions. The object for testing was a wire with a diameter of 0.5 mm from the current-carrying cable core without insulation made of the 8176 aluminum alloy. The experimentally established dependencies demonstrate a decrease in the aluminum wire sample mass with their exposure to each media under consideration for a certain time. Analysis of the obtained dependencies made it possible to evaluate the 8176 alloy corrosion resistance in those media.
