Annealing textures of 3N (35 ppm Fe) and 4N (7 ppm Fe) aluminum foils for electrolytic condenser produced by intermediate annealing-light rolling processes were examined. The aim is to clarify (1) mechanisms of difficulty of cube texture formation in 3N foils as well as in thinner foils, (2) dependence of suitable intermediate annealing temperature on iron contents, and (3) significance of intermediate thermo-mechanical treatments and effect of pre-annealing on the cube texture formation. It has been elucidated that the significance of intermediate thermo-mechanical treatments should be pursued to the following nature of the development of cube texture; the development in thin foils depends distinctly on the nucleation process and the primary recrystallization grain size distribution of cube and R components which are extensively affected by the iron content less than 0.01 mass%.
