  • Composite aluminum foil for use as electrode in electrolytic capacitor
    Patent number: 4510207
    Abstract: Described is a composite aluminum foil for use as an electrode in an electrolytic capacitor, having an aluminum core layer of purity greater than 99.995% clad on each side with an aluminum outer layer of purity 99.0 to 99.99%, which has a rich proportion of a cubic texture, i.e., a predominant occupancy of the crystallographic plane of Miller indices (100) substantially parallel to the surface of the foil. The core layer may contain both or either of copper and iron in an amount of 10 to 40 ppm.
