Oxyde noir

Black oxide is a chemical conversion coating that delivers a sleek matte-black finish while maintaining dimensional precision. This process enhances corrosion resistance, reduces surface reflectivity, and gives machined components a more durable and uniform appearance.

The result is a deep black finish that looks refined while offering practical benefits like corrosion resistance and reduced light reflection.

At Yicen Machining, we offer black oxide surface finishing for steel and stainless steel parts providing both function and form at a competitive price.

Our Process for Black Oxide Finishing

At Yicen Machining, each part goes through a rigorous process to ensure optimal results:

Cleaning and Preparation – Parts are thoroughly cleaned to remove any oils, rust, or surface debris.

Conversion Treatment – Components are submerged in a heated alkaline solution that reacts with the metal to form a black magnetite layer.

Sealing – After treatment, parts are rinsed and sealed with oil, wax, or a polymer coating to improve corrosion resistance and surface durability.

This method is fast, reliable, and suitable for both complex geometries and high-precision components.

Advantages of Choosing Black Oxide

When you choose black oxide surface treatment from Yicen Machining, you benefit from:

Corrosion Protection – Especially when sealed, black oxide offers strong resistance to rust and oxidation.

Dimensional Precision – Adds only a thin layer (around 0.25 µm), preserving critical part dimensions.

Reduced Reflectivity – Matte finish minimizes glare, ideal for tactical and optical applications.

Enhanced Durability – Increases wear resistance and reduces friction in moving assemblies.

Aesthetic Appeal – Provides a clean, professional black finish for high-visibility components.

Cost Savings – More affordable than many plating or painting alternatives, without compromising performance.

Where Black Oxide is Used

Black oxide finishing is used in many industries where appearance, wear resistance, and corrosion protection are essential:

Firearms & Tactical Gear – Non-reflective finish improves concealment and durability.

Automotive Components – Used on gears, shafts, and fasteners to resist wear and rust.

Industrial Tooling – Helps reduce glare while improving tool longevity.

Mechanical Assemblies – Provides protection for moving parts such as bushings, pins, and spindles.

Architectural and Decorative Parts – Delivers a refined black look for hardware and fixtures.
