This paper presents the effect of fly ash as reinforcement on mechanical behavior of aluminum alloy. 5% by weight of untreated fly ash was used as a reinforcement to fabricate the composite samples by sand casting technique. Tensile, Hardness and Fatigue tests were carried out for the samples. It has been observed that by the addition of fly ash to aluminum alloy improves the ultimate tensile strength(UTS) and hardness by 15.87% and 5.64% repectively as compared to sand casted simple aluminum alloy.Similarly fatigue tests reveal that fly ash reinforced aluminum composite has greater fatigue life than the unreinforced aluminum alloy.
