Design engineers requiring predictable chassis grounding and a superior black finish for aluminum electrical assemblies and components have a new option with the Lumiclad black oxide process from Birchwood Casey. 

Electrically conductive and clean, the finish is designed to add value to all types of aluminum electrical/electronic components and assemblies. With electronic applications in automotive, communications, computer, military, and aerospace, the black finish also ensures effective chassis grounding of critical components in assemblies.

Unlike black anodizing that is non-conductive, limiting its usefulness in electrical and electronic applications, the Lumiclad finish has proven its capabilities in critical grounding applications, says Birchwood Casey. The patent-pending process takes 30 min and develops a uniform coating thickness of .000060 inches (1.5 µ) that will not close down hole diameters or change critical part dimensions. The smooth black finish has a slightly porous crystal structure that absorbs an optional topcoat such as a dry-to-touch sealant, light oil, or clear polymer.
