Susceptibility of aluminum alloys to corrosion in simulated fuel blends containing ethanol

Abstract The compatibility of aluminum and aluminum alloys with synthetic fuel blends comprised of ethanol and reference fuel C (a 50/50 mix of toluene and iso-octane) was examined as a function of water content and temperature. Temperatures examined ranged between 20 °C and 200 °C and water content ranged between sub 50 ppm and 10% by volume. Commercially pure wrought aluminum and several cast aluminum alloys were observed to be similarly susceptible to substantial corrosion in dry (
