## Abstract

US military detail specification for chromate and non-chromate chemical conversion coatings on aluminium — the conversion coating equivalent of anodize for applications requiring electrical conductivity (e.g. RF grounding, antenna housings) where anodize's insulating film is incompatible. Defines Class 1A (full corrosion protection) and Class 3 (electrical conductivity-preserving) coatings. Increasingly important as the industry moves from hexavalent chromate to trivalent chromium and non-chrome alternatives.
