The tensile test of die-cast aluminum alloy were carried out in 1.0% sodium chloride solution at room temperature, and the stress, strain and open-circuit potential were measured during the test. As a result, it was found that the stiffness of the as-cast specimen was lower than that of the casting specimen in the elastic region, but the stress-strain relationship was almost same in the plastic region. In addition, compared to the as-cast specimen, the polished specimen was susceptible to corrosion and it became clear that the damage of the film was early.
