Black Oxidation

It is a chemical conversion finish for ferrous metals that upgrades surface aesthetics and provides essential corrosion resistance.

This treatment is widely high-wear components such as gears, gauges and critical firearm assemblies due to its advantages:

Maintains original dimensions: By altering the molecular structure of the substrate’s top 1.5 to 2.5 microns, this process adds no raw material to the component—perfectly preserving its original dimensional tolerances.

Enhances corrosion resistance: Combined with oils or sealants, the black oxide layer acts as a durable carrier for moisture-displacing compounds, providing critical surface protection.

Boosts wear resistance: The porous oxide finish traps and holds lubricants, reducing friction and extending the service life of moving parts.

Improves appearance: It delivers a uniform matte or glossy black surface that significantly upgrades the final look of the component.

Reduces light reflection: Exhibiting excellent light absorption properties, the deep black coating minimizes optical reflections and eliminates glare.
