The purpose of this work is to study the evolution of the microstructure, mechanical and electrical properties of an aluminum alloy, depending on the deformation level and annealing treatment. The study was conducted on an AGS type aluminum wire used by the international company ENICAB of Biskra for electrical cabling. These wires were obtained by the cold drawing process undergo annealing treatment at the temperature 170 °C for different holding times (10 minutes, 4 hours and 20 hours). Various analysis techniques were used in this study to monitor the microstructural evolution, mechanical and electrical properties. The optical and electron microscopy, micro-hardness, tensile test and electrical resistivity measurement were used. It was noted that the drawn aluminum wire causes an increase in the micro-hardness. On the other hand, the annealing at 170 °C does not cause significant changes on the evolution of the mechanical strength and electrical resistivity compared to the deformed state. Furthermore there has been a remarkable decrease in elongation after 4 hours at 170 °C annealing compared to the deformed state.
