Investigation was carried out to understand the influence of heat treatment on structure and corrosion resistance of 8090 aluminium alloy in ethanol solution for ethanol fuel tank application. Heat treatments were subjected to solutionizing at temperature 525°C for 4 hours to infiltrate the aluminium crystal by copper atoms and aging at temperature 190°C with different time to bring copper and lithium atoms out of aluminium crystal during aging process. X-ray diffraction was performed to investigate the phase of each sample with different aging time. Electrochemical experiments were conducted to investigate the corrosion resistance in 3, 5% and 7% NaCl solution and 70% and 96% of ethanol solution. The results show different corrosion behaviour of this material. Heat treatment on this material shows significant different results.
