  • Patent number: 5688606
    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.

  • Patent number: 5637160
    Abstract: There is provided a machinable .alpha.+.beta. brass containing bismuth and phosphorous. By maintaining the phosphorous content within a critical range, the alloy exhibits good elevated temperature tensile elongation in the temperature range of 100.degree. C.-350.degree. C. without a decrease in machinability due to phosphide formation. In preferred embodiments, the alloy further contains a tin addition for enhanced corrosion resistance. The combination of tin and phosphorous provides enhanced corrosion resistance to the alloy than could be predicted from either addition alone.

  • Patent number: 5403975
    Abstract: A process for producing electronic package components from an aluminum alloy is disclosed. The components have a black color through integral color anodization. The desired color, thickness and surface finish are achieved by regulation of amperage during anodization. The amperage is rapidly raised to in excess of 80 amps per square foot and then allowed to gradually decrease as a function of oxide growth.
