Rapidly solidified Al-Si alloy foils with Si content in the range of 0-20mass% were prepared by single roll method. Continuous and sound Al-Si foils were fabricated with Si content in the range of 0-16mass%. Dents on the roll contact side surface of foil disappeared when Si content became greater than 4mass%. Good surface characteristics of 99.99mass% Al foil was affected by thickness, but in the case of Al-Si alloys it was not affected. There was no effect on the uncontact part in the wetting pattern by Si content. Roughness on the roll contact side surface of the foil depended on the Si content, and Si content greater than 8mass% made the surface smooth. Contact area between roll and foil increased with increase of Si content within the range of less than 8mass%.
