Abstract The microstructure evolution and the mechanical properties are presented in the drawing process of A6 aluminum conductor in this paper. The results show that the tensile strength of A6 aluminum conductor shows three-stage changes in the drawing process. In the case of extrusion deformation, grains were elongated in the drawing direction and <111> fiber texture formed. In the I-stage, aluminum conductor was strengthened by the obvious increase of dislocations. Heavy deformation led to the formation of texture in the aluminum conductor in the drawing process, which caused the further improvement of the tensile strength in the III-stage. The tensile fracture of A6 aluminum conductor exhibits ductile fracture with dimples. The strength variation in combination with the microstructure in the drawing process of A6 aluminum conductor was also discussed.
