The results of this paper relate to a development program designed to improve the corrosion resistance and mechanical properties of Al-2.5Mg alloys, by the addition of chromium and silicon, for desalination applications. The effect of 0.1 wt to 0.3 wt percent chromium addition on the mechanical properties and corrosion resistance of Al-2.5Mg in the Arabian Gulf water has been investigated. The results show that chromium addition has beneficial effects on the mechanical properties and corrosion resistance of the Al-2.5Mg alloys. A near optimum combination of mechanical properties and corrosion resistance is obtained by 0.2 wt and 0.3 wt percent chromium addition.
