New requirements of the automotive industry, concerning lightweight and non-corroding construction, demand new production methods. Due to this the Hot Air Forming process of aluminum alloys are specially interest. The disadvantage of aluminum alloy is the poorer formability compared to steel. Hot Air Forming process is one of the forming process receiving recent attention. In the current study, fabrication of aluminum subframe has been attempted using seam and seamless aluminum tubes. On the base of hot workability of the extruded tube and PAM-STAMP simulation results, optimum condition for fabricating aluminum subframe parts by Hot Air Forming could be determined.
