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.
