The aim of the present study is to quantify the selective removal of tin and phosphorus in phosphor bronze wire exposed at shore site at Mandapam after mechanical polishing. The samples were withdrawn from exposure monthwise and cumulatively. Corrosion rates were determined after pickling the corrosion product. The stripped corrosion product was analysed for tin using atomic absorption spectrophotometer (AAS) and for phosphorus using photocolorimeter. These were plotted along with corrosion rates. The average values of tin and phosphorus in the corrosion product are 4.6% and 12.8% respectively, whereas the parent alloy contained phosphorus: 0.4%, tin: 5% and copper: balance. The severity of the atmosphere for corro sion is discussed on the basis of meteorological data. The chemical analysis is supported by the scanning electron micrograph (SEM)
