What Is Black Oxide?
Black oxide is a chemical conversion treatment that forms a thin black oxide layer on the surface of steel or stainless steel. Unlike paint, it changes the metal’s surface rather than covering it with a thick coating.
The treatment produces a black appearance with minimal dimensional change. An oil finish is then applied to help protect the parts against corrosion.
A Black Finish That Preserves the Details
Black oxide is an option for parts that need a dark appearance without the buildup of a thick coating.

Send Your Project DetailsOur Black Oxide Process
From cleaning to the final oil treatment, each stage prepares the finish result your parts need.
The parts are cleaned to remove oils, grease and surface contaminants before the black oxide treatment.
The parts are immersed in a heated chemical bath that converts the metal surface into a thin black oxide layer.
After treatment and rinsing, an oil finish is applied to help improve corrosion resistance.
