Du-Lite’s black oxide chemicals

Black Oxide Finishes Are Used When a Long-Lasting, Durable Protective Black Coating is Required.

Du-Lite’s black oxide chemicals are used in the chemical blackening process for carbon steel parts. We also provide other chemical processes to blacken stainless steel, silver solder, cast iron, brass, or copper. The black oxide process penetrates the metal surface to provide durable protection without altering the physical dimensions or properties of the metal itself.
