Black Ziron

Zinc Iron alloy deposit for extended corrosion resistance and environmental durability.

Technical Data Sheet - Black Ziron 

Anoplate’s Black Ziron is a proprietary electrodeposited zinc-iron alloy which provides excellent corrosion resistance and durability over conventional zinc plating.

Black Ziron uses a proven alkaline, non-cyanide plating chemistry for even thickness distribution and excellent alloy distribution, ensuring that the corrosion benefits of the alloy reach in to the deepest geometries.

Black Ziron utilizes silver-free black chromate posttreatment. This ensures that the color will not fade to green over time, like conventional black zinc plating. Additionally, since there are no precious metals in the chromate, the cost of Black Ziron will not fluctuate with the silver market.

Customer Challenge → Anoplate Solution

Anoplate’s Black Ziron finish solved a corrosion problem on a naval communications housing. The assembly was a mixture of zinc-plated steel, passivated stainless, and brass components that were all exposed to the extremes of temperatures, humidity, and salt wash that plagues the deck of today’s warships. The zinc-plated steel components were rusting, specifically around the interface between dissimilar materials and where sea spray would pool. Secondly, the black zinc would fade to an olive-drab green color over time. Black Ziron was evaluated over a 3-month period on-board the ship and was found to be the perfect solution for both corrosion resistance and black color.
