Abstract: A ternary alloy (Al20Cu20Mg) high strength metallic particulate was reinforced in a base matrix binary alloy of Al-4Mg to prepare a metal-metal composite. This was investigated for corrosion behaviour. High Strength Alloy particulate (HSAp) of non-uniform size from the ternary alloy was utilized with weight proportions of 5%, 10%, and 15% to prepare composites using stir casting process. The prepared composites were extruded into circular rods of 14 mm diameter. The potentiodynamic polarization test was conducted on the extruded specimen and it is found that the pitting corrosion was improved considerably by the addition of Al20Cu20Mg as reinforcement in Al-4Mg.
