Abstract
Aluminum foil for an electrode of an electrolytic capacitor is disclosed. The foil comprises at least one core layer adapted to prevent the growth of pits by electrolytic etching, and outer layers formed on both surfaces of the core layer. A large number of etching pits are produced in the outer layers. In a modification, the core layer contains more iron than the outer layers. Again in a modification, the core layer is covered or contained with aluminum oxides or hydroxides.
