    Abstract: The challenges posed by the high thermal conductivity and complex chemical composition of aluminum alloys can be overcome by selecting an appropriate aging temperature. This paper investigates the effects of aging processes on the microstructure and properties of 2319 aluminum alloy fabricated by CMT cladding. Electrochemical corrosion tests were conducted on three samples aged at different conditions: 160°C×9 h, 175°C×9 h, and 190°C×9 h. The results indicate that as the aging temperature increases, the mechanical properties and hardness of the alloy improve. The findings provide significant reference for further exploration of the impact of aging temperature on the properties of aluminum alloys.
