About Black Oxide
Black oxide, also known as blackening (similar to Alodine) , is a chemical conversion coating used to provide a layer of black corrosion protection on various types of metal surfaces, particularly steel and iron.
The process of black oxide involves immersing parts in a hot bath containing various chemicals to convert the surface of the material into magnetite, thereby forming a black oxide layer. This process will not have a significant impact on the size of the parts, so there is no need for special steps to cover or cover the parts.
In addition, the black oxide immersed in oil can provide higher corrosion resistance. Because after the black oxide, a layer of oil film is usually applied, which helps to provide additional corrosion protection and reduce contact between the metal surface and the external environment.
Material Selection
We offer a wide range of materials for black oxide to meet the diverse needs of various industries. Our selection includes metals, plastics, and composites to ensure that your parts are manufactured with the best-suited material for your application. Below are some of the materials we commonly work with:

Surface Finishing for Black Oxide Services
| Category | Description | Material | Color | Texture |
|---|---|---|---|---|
Anodizing
|
Anodizing is an electrochemical process used to enhance the corrosion resistance, appearance, and surface properties of metal parts, particularly aluminum. | Aluminum, Metals | Clear, black, grey, red, blue, gold | Rough, smooth, metallic |
Powder Coating
|
Powder coating is a popular and environmentally friendly method of applying a protective and decorative finish to various types of metal and even some non-metal surfaces. | Metals | White, Black, RAL and Pantone | Glossy, fine, hardness |
Polishing
|
The primary goal of polishing is to create a smooth and reflective surface by removing imperfections, scratches, and irregularities. | Metals | Silver gray | Bright, mirror, silk |
Chromate
|
Chromate, commonly known as a chemical thin film, is a conversion coating used as a corrosion inhibitor on aluminum. | Aluminum | Clear/ Slight yellow tint | Satin |
Bead blasting
|
Bead blasting, also known as abrasive blasting, is a surface preparation technique used to clean, finish, or texture a surface by forcibly propelling small, spherical abrasive materials, called "beads" or "media," at high speeds onto the surface being treated. | Aluminum, copper, stainless steel, steel | N/A | Grainy, slightly matte texture |
As machining
|
Machining is a subtractive manufacturing process in which a machine tool, typically a cutting tool, removes material from a workpiece to achieve the desired shape, dimensions, and surface finish. | Metals | N/A | Smooth, glossy finish |

FAQ
1. What materials can be treated with black oxide coating?
Black oxide is commonly applied to steel, stainless steel, copper, and other ferrous metals to improve corrosion resistance and appearance.
2. How does black oxide coating protect metal parts?
It creates a thin, black protective layer that reduces surface corrosion and enhances wear resistance without adding significant thickness.
3. Is black oxide coating suitable for outdoor applications?
While black oxide offers some corrosion protection, additional sealing or coating is recommended for prolonged outdoor exposure.
4. What is the typical thickness of a black oxide coating?
The coating is very thin, usually around 0.5 to 1 micron, maintaining tight dimensional tolerances.
5. Can black oxide coating be applied to parts with tight tolerances?
Yes, due to its minimal thickness, black oxide coating does not significantly affect part dimensions.
6. How do you ensure the quality of black oxide coatings?
We perform visual inspections, adhesion tests, and corrosion resistance tests to ensure coating performance.
7. What is the lead time for black oxide services?
Lead times typically range from 3 to 7 business days depending on order size and complexity.
8. Can black oxide coating be combined with other surface treatments?
Yes, it is often used in combination with oil or wax sealers to improve corrosion resistance.
9. How should parts be prepared before black oxide treatment?
Parts must be thoroughly cleaned and free of oils, rust, and scale to ensure proper coating adhesion.
10. Are there any environmental concerns with black oxide processing?
We follow strict environmental regulations and use eco-friendly waste treatment methods to minimize impact.
