Tube hydroforming has been noticed as a forming method for complicated hollow shape parts. This process has many advantages compare to conventional forming methods, so steel exhaust pipes and chassis parts have already been mass-produced by using this process. On the other hand, aluminium parts have only been applied to suspension in Europe, but deformation properties of aluminium alloy tubes have not been made clear yet. In this paper, hydroformability of aluminium alloy tubes was introduced by using experimental data, and noticeable points on hydroforming of aluminium alloy tubes were explained.
