Summary:[Display omitted] The microstructure and mechanical properties of 1060/6063 Al alloys joint fabricated by porthole die extrusion were investigated. A sound welding interface of 1060/6063 Al alloys was obtained, and the welding quality can be further improved using higher welding chamber. Complete dynamic recrystallization (DRX) occurred during porthole die extrusion, while the DRXed grain size of 6063 Al matrix was always much smaller than that of 1060 Al matrix. The height of welding chamber had an significant effects on the microtexture of the extruded profiles. The profiles extruded using welding chamber with a height of 10mm exhibited highest tensile strength and elongation. On the contrary, the joining of 1060/6063 Al alloys using flat die is not acceptable, where many cracks appeared at the welding interface and only partial DRX occurred.
