ALUMINUM MATERIAL FOR ELECTRODE OF ELECTROLYTIC CAPACITOR AND METHOD FOR PRODUCING ALUMINUM FOIL FOR ELECTRODE OF ELECTROLYTIC CAPACITOR, AND ELECTROLYTIC CAPACITOR |
摘要 |
An aluminum material for electrolytic capacitor electrodes, the aluminum material having aluminum purity of 99.9% or more, consisting of: Si: 2 to 50 ppm; Fe: 2 to 50 ppm; Cu: 15 to 150 ppm; Zn: 1 to 80 ppm; Pb: 0.1 to 3 ppm; at least one of Zr and V: 11 ppm or more, a total content of the at least one of Zr and V being 11 to 100 ppm; and the balance being Al and impurites, wherein a content of B is controlled to be 2 ppm or less. In the aluminum material, Ti: 1 to 30 ppm, Mn group composition (at least one of Mn, Ga, Mg and Ca): 1 to 50 ppm in total, and In group composition (at least one of In, Sn, Sb): 1 to 30 ppm in total are selectively added. A method for manufacturing an aluminum foil for electrolytic capacitor electrodes according to the present invention, comprises the steps of: rolling the aforementioned aluminum material into a foil; and performing final annealing of the foil at the temperature of 430 to 580 DEG C. |
