Abstract
PURPOSE: To obtain an Al alloy foil for the cathode of an electrolytic capacitor which foil has an increased electrostatic capacity and an enhanced mechanical strength, by a method wherein a continuously cast plate of an Al alloy containing limited amounts of Cu, Ti and B is subjected to cold rolling and foil rolling.
CONSTITUTION: An Al alloy containing 0.1W1.0% of Cu, 0.002W0.05% of Ti and 0.0005W0.05% of B, the balance being Al and unavoidable impurities such as Si, Fe or the like, is continuously cast and rolled to produce a plate. The plate is subjected to cold rolling and foil rolling to obtain an Al alloy foil. The surface of the foil is etched to produce a rugged foil surface. The alloy foil has a capacity-increasing effect enhanced by the addition of the limited amounts of Cu, Ti and B, and its corrosion loss at the time of etching is reduced to contrive an enhancement of the mechanical strength.
