05 Sep Comparing Zinc Alkaline Plating to Acid Zinc Plating
Both zinc alkaline plating and acid zinc plating (chloride) can be applied to a wide variety of base metals and alloys. Choosing one over the other is largely a factor of the specific requirements of the coating, the base metal, and what will happen to the part after the plating process is complete.
It is important for our team at DeKalb Metal Finishing to understand the application of the part and the material used to ensure that our plating technology is appropriate for your project.
Part Requirements and Zinc Alkaline Plating
Our focus has centered on alkaline zinc plating. Many of our parts have complex geometries and require even plate distribution. Zinc alkaline plating provides our customers with excellent ductility, uniform plating thickness, excellent ductility, and controlled distribution of zinc across the entire surface of the part.

For us, typical automobile parts where a zinc alloy is used and require zinc alkaline plating include:
- Anti-Vibration Components
- Door Hinges / Locking Mechanisms
- Horn Housings
- Transmission Rings
- Other interior components without direct weather exposure
Some people are surprised to learn that zinc alkaline plating is environmentally friendly and compliant with RoHS and SVHC. Our team would be happy to discuss the various options for your project to ensure all your needs are addressed.
