Abstract

PURPOSE: To obtain alloy foil having high capacitance, small loss on corrosion and superior mechanical properties by adding a specified percentage each of Fe, Cu, Ag, Zn, Cd, Ga, In Sn and Ni to high-purity Al as a base metal.
CONSTITUTION: To high purity Al as a base metal are added, by wt., 0.0004W 0.0015, preferably 0.0005W0.001% Fe, 0.001W0.008, preferably 0.002W0.007% Cu and 0.00001W0.001, preferably 0.00005W0.0008% in total of at least one of Ag, Zn, Cd, Ga, In, Sn and Ni. The purity of the high purity Al is ≥ about 99.99% in general.
