<p>There is provided an anodizable aluminum substrate (12) 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 (14) increases the breakdown voltage by decreasing corrosion. A preferred sealant (30) is an epoxy cresol novolac having a low room temperature viscosity that cures to a highly cross-linked polymer.</p> |
