Abstract

PURPOSE: To reduce loss on etching and to increase the electrostitic capacity of foil by adding a prescribed amount of Bi to Al having a specified purity or above.
CONSTITUTION: The titled alloy foil is obtd. by adding 0.00005W0.001wt% Bi to high purity Al having ≥99.9wt% purity. When Al is etched after adding such an adequate amount of Bi, the density of surface recesses of foil is increased. Accordingly, the electrostatic capacity of the foil is increased.
