Abstract
PURPOSE: To carry out uniform and effective etching for increasing the surface area of the cathode foil of an electrolytic capacitor by dissolving an adequate amount of Cu to prepare a solid solu. in an Al alloy for the foil and adding a specified alloying element.
CONSTITUTION: The surface area of Al foil as the cathode of an electrolytic capacitor is increased by etching as one of means of increasing the capacitance of the capacitor. At this time, the Al foil is made of Al alloy having a composition contg. 0.05W1% Cu and one or more kinds among 0.05W0.2% Zn, 0.05W0.8% Cr, 0.1W 0.8% Co, 0.1W0.8% Ni, 0.001W0.3% Li, 0.001W0.3% Ca and 0.1W1% Zn. When the cathode foil of the capacitor is manufactured using this Al foil, the area increasing rate can be made higher without producing no corrosion pit by etching for increasing the surface area, and the capacitance of the capacitor can be increased.
