Corrosion Resistance of Hot Dipping Aluminized Wire

The corrosion resistance of aluminized wire is remarkably higher than that of galvanized wire. However, very few reports have so far been made of the corrosion resistance of the aluminized wire produced in Japan. In this report, the corrosion resistance of aluminized wires produced by the authors was studied in various corrosive conditions.The following results were obtained.(1) The corrosion resistance of aluminized wire in acidic solution was higher than that of galvanized wire and somewhat higher also in the atmosphere containing acidic gas. However, the former was lower than the latter in most alkaline conditions.(2) The corrosion resistance of aluminized wire in hot water was remarkably higher than that of galvanized wire.(3) The corrosion resistance of aluminized wire in sea water was 2 or 3 times as high as that of galvanized wire. Even in the marine atmosphere or in alternate immersion of sea water and atmospheric exposure, aluminized wire was considered to be more suitable for use as compared with galvanized wire.
