For productions of double rolled foils in aluminum alloy, it is important to obtain fine mat surface. Because pin holes on the thin foils formed by connection corrugation wave on mat surface and oil pit on bright surface. We have investigated that size and morphology of intermetallic compounds, linking with pin hole numbers. As results, it become clear that spherical AlFeSi compounds increased non-flattening mat surface than plate AlFe compounds. The spherical AlFeSi compounds and the pin hole numbers in the foils were decreased by increasing Fe/Si ratios or homogenization annealing at higher temperature. These facts suggest that pin hole formation on the fine mat surface is more difficult than on the rough mat surface with spherical AlFeSi compounds.
