Attempts have been made to disperse fine Cu filings in aluminium matrix by conventional stir cast technique to produce metal-metal composites. SEM-EDX analysis shows a gradual variation in chemistry from dispersoid to the matrix. Production of composites show an ease of dispersion of metallic dispersoid compared to a ceramic one. Corrosion study in terms of loss in weight in acid media has been investigated. Composite show a lesser dissolution rate compared to the alloy having same composition, at different concentrations of the corrosive media. Composite with higher concentration of dispersoid show reduced corrosion resistance.
