In recent years, the small diameter aluminum tubes have been widely utilized for digital devices and medical devices. The size of these instruments should be minimalized since the usage of the small diameter tubes has been increased drastically. However, the small diameter tube loses its conventional characteristics due to the size effect. Thus, for tube forming, it is necessary to clarify the deformation characteristics of the small diameter tubes. In this paper, the formability of warm bulge forming using the small diameter A1100 aluminum tube with 2.0 mm outer diameter and 0.2 mm thickness was investigated. As a result, the effect of different temperatures and various internal pressure in warm bulge forming using the small diameter A1100 aluminum tubes has been clarified. Furthermore, it is confirmed that the variation of the internal pressure loading rate affects the deformation characteristics of the small diameter A1100 aluminum tubes. The fracture pressure at 200˚C is approximately 56% lower than the one at RT. From these results, we confirmed that the warm bulge forming system could improve the formability of the small diameter A1100 aluminum tubes.
