Aluminium based alloys are appropriate materials for structural applications in the aircraft and automotive industries. Because they are ductile, highly conductive, high strength to weight ratio and they are heat treatable. The material selected for this research work is Al 2024 alloy which is commercially available. Present paper involves the study of Tafel polarisation and microstructural behaviour of Al 2024. The corrosion studies for Al 2024 were carried out by using electrochemical analyser in various concentration of corrosion medium such as HCl at laboratory temperature. From microstructural studies, intergranular corrosion with traces of pitting was observed in the samples when immersed in the HCl solutions. Results indicate that Al 2024 alloy shows more resistance to corrosion.
