The 4 types of Zinc Plating explained
18 March 2022
Corrosion is the age old enemy of some metals. Whilst in most cases, rust can be cured, it can often be expensive and so prevention can not only be better than cure, but also cheaper in the long run.
Zinc Plating electronically applies a layer of Zinc onto the metal’s surface, such as Iron or Steel, where it serves as a corrosion resistant barrier. Here we’ll explain about the 4 different ways it can be done.Yellow Zinc Plating is more common in the automotive industry, providing mid-level protection against corrosion making metals ideal for use outdoors.
Blue or clear Zinc Plating offers a lower level of corrosion protection but is kinder on the environment. Typical uses include machine parts and fixings or ornamental finishes thanks to its attractive finish.
Black Zinc Plating uses Black Oxide, Black Plating or both, providing a range of finishes from dark Olive to Pure Black. The Black Oxide is particularly more resistant to rust and is also used for decorative finishes.
Acid Zinc Plating is quite different to the first three methods as it does not introduce Cyanide into the bath. It is ideal for hard to place surfaces and offers superior coating covering power.
