Abstract: The hardness, room temperature tensile properties and electrical conductivity of a 7XXX series aluminum alloy plate in T6I76, T73 and T6 under three aging conditions were studied and the local corrosion properties of the alloy were investigated by means of intergranular corrosion tests, exfoliation corrosion tests,polarization curve and electrical impedance tests. The results show that the strength and hardness of the T6I76sample are equivalent to those of the T6 sample, but the local corrosion ... More
