Black Oxide Conversion

Also known as metal blackening, oxidizing, oxiding, gun bluing usually applied to instruments and small machine parts via immersion.

Similar to phosphate conversion, the treatment causes an oxide layer to form over the surface providing a protective layer. The corrosion-resistant coating is a non-metallic black iron oxide. The process results in an excellent coal black finish on iron, steel or steel alloys parts.

This process can be applied on steel, iron, and stainless steel alloys. Our bulk processing capabilities allow us to handle large and small production runs with quality workmanship and quick turnaround time.

Cellulose lacquer, oil and waxes can be used over the coating for a more decorative and protective finishing.
