Why Choose DeKalb for Zinc Iron Plating?

If you want parts to have a beautiful black finish while providing extreme corrosion protection, zinc iron is one of the best plating options you can choose. This process has sacrificial properties which improves metal’s resistance to rust and corrosion. With zinc iron plating providing enhanced protection and many other benefits, who should you go to for your plating needs? Here are several good reasons to choose DeKalb Metal Finishing:

Alkaline (Non-Cyanide) Electrolyte

Electroplating has been around since the early part of the 19th Century. During the early years, cyanide compounds were use in an acidic process. This created an effective coating, but cyanide can be extremely hazardous. Over the past few decades, some companies have changed to an alkaline method which does not use cyanide. It is much safer for workers and the environment. Additionally, it offers much more consistent plating thickness between high and low current density resulting in a more even finish.

Why Mix Zinc with Iron?

Zinc is an excellent anti-corrosion element, but iron is not. In fact, it rusts quite easily, so why would anyone want to put iron in with zinc? Protecting iron components and parts can be a challenge at times. Although zinc protects well, when you utilize zinc iron plating, you enhance iron’s ability to resist corrosion so if you need extra protection, iron and zinc can be the right choice.

Quality with DeKalb

Some black zinc plating can be dull and present a “grey-ish” appearance. When iron is added to the process, the parts look significantly darker and become consistently black in color. We make sure the iron content remains constant throughout the process creating a high-quality result.
