Black Oxide Overview
Black oxide is a chemical conversion finish used on ferrous materials, stainless steel, zinc, copper, and copper-based alloys to produce a uniform black appearance. Parts are cleaned and prepared before treatment, with post-treatment selected for the material and application.
- Matte black appearance:
The finish provides a uniform black appearance and reduces light reflection.
- Tight-tolerance parts:
Black oxide is suitable for parts with tight dimensional tolerances.
- Corrosion protection:
Post-treatment with oil, wax, or lacquer can improve corrosion resistance.
- Sliding components:
The finish can help reduce adhesive wear between parts that slide against each other.
