We offer rack and wired black oxide conversion coating on steel.

Black oxide is not a electroplating process. It is a conversion process, which changes the surface of the steel a dark blue to black color. The part is then immersed in a water dissipating oil which also increases the corrosion resistance. The main benefit of this process is that it does not change the dimensional properties of the part.

If you have any questions about black oxide, feel free to
contact us.
