Paper Title:
On-Line Aging to Improve the Tensile Strength and Conductivity of Cold-Drawing AA6201 Wires
  Abstract

AA6201 with main compositions of Mg-0.5 wt % and Si-0.5 wt %, is a typical electric conductive alloy which shows remarkable combination of high strength and high electric conductivity after heat treatment. Cold working and aging treatment process have a significant effect on its mechanical properties and conductivity. Shearing/Cooling Rolling process (SCR) was proposed to produce the feedstock for all aluminum alloy conductor. The effects of cold drawing on the properties of the alloy produced by SCR process were investigated. There are two methods used in the study, one is the cold drawing and aging heat treatment (CDAH) to produce the wires, the feedstock prepared by SCR and on-line solution, the other is the feedstock prepared by SCR and on-line solution-aging heat treatment plus cold drawing (AHCD). Results show that the AHCD can improve the properties of products due to sub-structural hardening. The tensile strength and equivalent conductivity of the alloy are 315 MPa and 55.03 % IACS respectively, and are much better than those characteristics of the alloy produced by the conventional process (295 MPa, 52.5-53.0 % IACS).
