The corrosion rates of commercially available 3004 aluminium alloy, 70130 brass and phosphor bronze were determined by exposure in the tropical marine atmosphere of Mandapam Camp. Weight-loss measurement was employed in computing the corrosion rates. The monthly corrosion rate of brass and phosphor bronze, and the quarterly corrosion rate of aluminium alloys were in line with the aggressiveness of the environment decided by the salinity value, temperature and humidity. The corrosion products formed on all the three alloys tested were compact and adherent. The direct attack of pollutants on the metals for further corrosion was hindered by the presence of these layers, and their protective nature was explicit from the exponential decrease of corrosion rates with time. In the high chloride containing atmosphere, the protection offered by the corrosion product on 3004 aluminium alloy was not so effective as that on the copper base alloys.
