Abstract

Tin addition to Cu‐7% Al in presence of 1% Fe and 1% Mn increases the corrosion resistance in HCl, H2SO4, NaCl and Sea Water. Tin addition in the absence of Fe and Mn causes embrittlement of the Cu‐7% Al alloy. However, in presence of Fe and Mn the alloy shows outstanding mechanical properties. Tin addition retards the anodic dissolution of oxide film and retards dealuminification. The corrosion resistance of the alloy could be increased by various heat treatments. Quenching from 650°C appears to be the most effective treatment. A high proportion of alpha phase and a greater dispersion of beta improves the corrosion resistance. The alloy developed could be used with advantage in heat exchange equipment and in various other marine applications.
