The main purpose of this work is to meet the need of an electrical cable manufacturer on the breaking of the wire aluminum AGS alloy. And also answer the question of the misfit properties prescribed by the provider to the final properties of the wire drawn.In this study we tried to follow the evolution of the properties of wire alloy during drawing. On the DL wire (wire for medium and high voltage line), it was found that the wire properties were very close to that recommended by the provider. However, the ML wire (wire for medium voltage line), for which the problem of rupture appeared, it was found that the differences were consistent between the properties of drawn wire and data prescribed by the supplier; these differences may vary from one arrival to another.Micrographic analysis by optical microscope revealed that there is no difference between the microstructure of the two wires; both have the same microstructure and acquire an elongated grain microstructure along the axis of the deformation during drawing. It should be noted that there was still a slight difference between a grain-size of both initials wires. The measurement of the microhardness showed a greater hardening of the DL wire compared to ML wire, during drawing. However, the electrical resistivity of ML wire is greater than the DL wire.
