Black Zinc Plating Services
Black Zinc Plating refers to the color of the chromate that is applied during the post plating process. It includes a layer of zinc applied to a parts surface followed by black chromate applied over the zinc.
Black Zinc is commonly specified for its dark appearance and protective properties. Black chromate offers additional corrosion protection by protecting the zinc plating and also provides a dark to deep black appearance depending on the surface condition of the part.
Considerations
Black Zinc chromate is an effective finish that provides excellent cosmetic benefits to most parts. However, it is not suitable for every application.
It is common to notice the color change from deep black to greenish-brown as the finish breaks down over time. Because of this color change, black zinc plating may not be the right finish for highly visible components with strict cosmetic requirements.
The appearance can also become compromised on parts requiring a sealer often producing streaks or a dull gray appearance, most noticeable on large flat components.

Benefits of Choosing Black Zinc
Black Zinc is an electrically conductive finish and offers superior corrosion protection over black oxide. Since the typical thickness is minimal, ranging from .0002” to .0006” it is also a good alternative to powder coat or e-coat for parts with tight dimensional tolerances.
- Minimize a parts visibility in a final assembled product.
- Disguises recessed lighting components.
- Common in automotive applications to camouflage components under the hood or seats.
- Cosmetic purposes requiring a uniform black finish
