In order to reduce the natural aging time of 2024 aluminum alloy, a new artificial aging technique of 2024 which aging time is shorter than that of the natural aging technique, based on the hardness and conductivity test and aging principle analysis, was proposed in this paper. The aging temperature of the new aging technique is 45±5.5℃, and the aging time is 12 hours. The aircraft staying time for structural repair will be greatly decreased by this new artificial aging technique.
