This paper is concerned with the rate-dependent material properties of an aluminum thin foil in the micro-scale. Micro-tensile tests were conducted for A1100 thin foils with thickness of 96 µm at various strain rates ranged from 1/s to 100/s using a High-Speed Micro Material Testing Machine (HSMMTM). The dimension of the test specimen was 1500 µm in the  gauge length and 300 µm in the gauge width. Test equipments designed and constructed for micro-tensile tests as well as a new jig system for easy installation and accurate alignment of a specimen between a specimen and the jig system. The jig mechanism developed enhances the reproducibility of experiments. Experimental results show that the flow stress of an aluminum thin foil increases more remarkable as the strain rate increases than the flow stress of an aluminum sheet with moderate thickness.
