Aluminum AA6082 extruded plates are solutionized at 520°C, 540°C, 580°C for 30 min. One set of samples were subjected to the natural aging heat treatment for 20 days, and 40 days other set samples were further subjected to artificial aging heat treatment where they are heated at 180°C for four hr to obtain the peak aging condition. Electrical conductivity is measured at different situations and correlated with the microstructural features and mechanical properties.
