Abstract: Cold drawing of extruded aluminium tubes not only improves the surface quality but also increases their strength, however ductility of the tubes decreases. To improve the ductility required for the following bending operations, tubes are heat treated after the cold drawing operation. To resolve an industrial problem, this research aims to determine the optimal heat treatment conditions for obtaining the required mechanical properties (yield strength, ultimate tensile strength and elongation to fracture) based on the ASTM 6063-T832 temper and also avoiding scraps caused by failure during the bending operation. Moreover, this research investigates the effect of the amount of prestrain imposed by cold drawing on mechanical properties after the heat treatment. Finally, it is interesting to know if the heating period inside the furnace before reaching the targeted temperature could be exploited as part of the required heat treatment to increase the productivity of the process.
