Zincalume COZ Description Application: A high corrosion-resistant zinc cobalt alloy plating process that utilizes acid chloride-based electrolytes and requires special chromate conversions, especially for black deposits. The Growel Advantage: It produces bright and uniform decorative and functional coating containing 0.2 - 1.0% cobalt. The deposits created are fine-grained and ductile. It displays physical properties like internal stress, weldability and lubricity similar to conventional Zinc coatings. It exhibits a higher hardness value and wear resistance. It is suitable for rack and barrel applications. get a quote
