Anodizing Services Surface Finish Specifications
Anodizing Type II Specifications
Type II anodizing produces metal parts with a thin oxide layer and moderate corrosion resistance. As a result, the quick turn anodizing process is ideal for parts requiring aesthetics and moderate protection.
| Color | Glossiness | Visual Appearance | Thickness |
|---|---|---|---|
| Clear | Glossy | It yields a clear, glossy finish that enhances the metal's natural luster without significantly altering its color. | 8-12μm |
| Clear | Matte | It imparts a clear, matte finish to the metal, giving a subdued and uniform appearance without high reflectivity. | 8-12μm |
| Black | Glossy | It produces a deep, glossy black finish that adds an attractive and protective layer to the metal. | 8-12μm |
| Black | Matte | Provides a subdued, matte black finish for those seeking a non-reflective and uniform appearance. | 8-12μm |
Advantages
- Enhanced corrosion resistance due to the formation of an unreactive oxide coating
- Improvement in aesthetic appeal as it offers a beautiful finish with different anodizing colors
- Insulative properties for parts that need dampening of electrical conductivity
- Anodized parts are easier to clean
Important Notes
- • Use sandblasting (#120) as a pre-treatment, or the machining marks on the surface cannot be completely covered.
- • Different materials, thicknesses, and lots will have a certain degree of color difference.
- • Non-standard and custom colors are available upon request.
Anodizing Type III Specifications
Type III anodizing parts with a thicker oxide layer which offers higher wear and corrosion resistance and surface hardness
| Color | Visual Appearance | Thickness |
|---|---|---|
| Clear | Introducing a non-conductive, thicker, and more wear-resistant oxide layer than standard anodizing. | 35-50μm |
| Black | It produces a deep, consistent black finish that is both durable and visually appealing. | 35-50μm |
Advantages
- High corrosion resistance
- The anodic film is harder than base aluminum
- Improvement in aesthetic appeal as it offers a beautiful finish with different color options
- Insulative properties for parts that need dampening of electrical conductivity
Important Notes
- • Different series of aluminum will show different colors.
- • Default mask fine holes and fine threads only. Special notes are required for other masking needs.
- • The workpiece needs to hook up a tiny substrate that is exposed after anodizing. RD defaults to hooking up threaded or countersunk holes. Specify if there is a specific hooking-up place.
Anodizing Type II vs Type III
Compare specifications to choose the right anodizing type for your application
| Properties | Type II | Type III |
|---|---|---|
| Corrosion Resistance | Moderate | High |
| Wear Resistance | Moderate | High |
| Coating Thickness | 8-12μm | 35-50μm |
| Appearance | Glossy and Matte finishes | More matte, highly durable |
| Environment Friendly | Yes | Yes |
Anodizing Finish Service Overview
Anodizing is an electrochemical process that improves a metal’s corrosion and wear resistance and cosmetic appearance. It is primarily for aluminum and involves connecting the part to the anode before submerging it in a sulfuric or chromic acid bath.
When a metal electrode is attached to the cathode, and current passes through the circuit, the cathode attracts positive ions from the aluminum part. In contrast, the aluminum part attracts O₂ ions from the solution.
The anodic part (aluminum) becomes porous due to the loss of cations and reacts with O₂ ions. As a result, this forms the oxide layer on anodized parts. There are several anodizing types depending on the voltage and the electrolyte.
