Anodized aluminum substrate having increased breakdown voltage
First Claim
Patent Images
1. A component for electronic applications comprising:
- an anodizable metal core having a yield strength in excess of 30 ksi; and
an anodic film coating at least a portion of said core wherein the alloy constituents within said anodizable metal core are substantially soluble in an anodization electrolyte thereby increasing the breakdown voltage.

Abstract
There is provided an anodizable aluminum substrate having an increased breakdown voltage. The increase in breakdown voltage is achieved by selecting an appropriate aluminum alloy and appropriate processing parameters. Sealing the anodic film increases the breakdown voltage by decreasing corrosion. A preferred sealant is an epoxy cresol novolac having a low room temperature viscosity that cures to a highly cross-linked polymer.
