Clear Anodized Aluminum CNC: Precision Machining with Superior Surface Protection
When you need both accuracy and longevity in a project, Clear Anodized Aluminum CNC cutting is the best way to go. We at Shenzhen Ruiyihang Technology Co., Ltd. make unique aluminium parts with anodising widths between 5 and 25 μm and tolerances of ±0.01-0.02 mm. Our engineering-based method has helped customers all over the world turn complicated plans into high-quality parts since 2008. With an average of 15 years of engineering experience, we can help with everything from quick prototyping (which can be done in as little as 3 days for simple parts) to full-scale production. We'll make sure that your aluminium parts meet all of your requirements and get better corrosion resistance and surface sturdiness.
What Makes Our Process Different?
We do more than just make things; we also come up with answers.
Our team looks over drawings and makes ideas better with you right there in the room. This direct contact cuts out agents and lowers the chance of mistakes. Before production starts, you get useful advice on choosing materials, designing the structure, and finishing the surface.
As a result? Better manufacturability and faster turn-around times.
Precision cutting with high-tech multi-axis tools is the first step in the process of making our products. After that, we use Type II anodising to add a protective oxide layer that keeps your aluminium parts looking like metal.

Material Selection for Your Application
Choosing the right aluminum alloy matters. We commonly work with three materials:
6061-T6 works well for general-purpose structural components. It offers good strength and excellent machinability.
6063 provides the best surface finish. If your part will be visible or decorative, this alloy delivers superior anodizing results.
7075-T6 suits high-strength applications. When your component faces demanding mechanical loads, this aerospace-grade aluminum performs.
Each material responds differently to anodizing. Our engineers help you select the best match for your specific requirements.
Precision That Accounts for Surface Treatment
Here's what many manufacturers miss: anodizing changes dimensions.
The oxide layer partially penetrates the base material and partially builds up on the surface. For precision parts, this matters.
We compensate for this during machining. Your critical dimensions remain accurate after anodizing. This attention to detail ensures your product components fit perfectly in assemblies.
Before anodizing, we achieve surface roughness of Ra 0.8 μm or better. This smooth foundation creates uniform coating adhesion and consistent appearance.
Surface Finishing Options Beyond Clear Anodizing
While clear anodizing preserves aluminum's natural look, we offer alternatives when needed:
- Black anodizing for modern aesthetics
- Custom colors including gold and blue
- Matte finishes with bead blasting
- Glossy finishes with polishing
- Hard anodizing (Type III) for wear resistance
Each finish serves different functional and aesthetic purposes. We guide you toward the option that matches your application.
Industries We Serve
Your industry has unique demands. Clear Anodized Aluminum CNC components have been provided to:
Electronics: Cases and covers that need to block electromagnetic waves and protect against rust
Coffee equipment: parts that meet FDA standards for items that come into touch with food
Robotics: Structures with exact standards and low weight
Automotive: Parts that do their job and need to last in tough situations
Industrial equipment: mechanical parts that need to be stable in terms of size
Because we've worked in many fields, we understand your problems before you even say them.
Quality Control at Every Stage
We inspect parts twice—after machining and after anodizing.
During machining, critical dimensions are verified to ensure accuracy. After anodizing, we check coating thickness, color consistency, and surface quality.
For appearance-critical parts, we pay special attention to visible surfaces. You receive components that meet both functional and aesthetic requirements.
When quality issues occur within the same month, we arrange remanufacturing within 1 week and cover shipping costs. That's our commitment to your satisfaction.
From Prototype to Production
Whether you need five parts or five thousand, we adapt to your volume.
Small-batch production benefits from our flexible approach. We don't require minimum order quantities that force you to over-invest.
For larger runs, our process control ensures consistency across every piece. The first part matches the last part in dimensions, finish, and quality.
Our typical sample production timeline runs 7 days. Simple parts can be completed in as little as 3 days. This speed helps you test designs and reach market faster.
FAQ
Q: What is clear anodizing?
Clear anodizing (natural color) preserves the aluminum's metallic appearance while improving corrosion resistance and surface hardness.
Q: Can clear anodizing be applied to CNC machined parts?
Yes, CNC milled, turned, or drilled aluminum components can be clear anodized without affecting dimensions.
Q: How does clear anodizing differ from colored or hard anodizing?
Clear anodizing retains natural aluminum color; colored anodizing adds color, and hard anodizing increases surface hardness.
Q: Will anodizing affect my part dimensions?
Anodizing creates a thin oxide layer. We account for this during machining to maintain your specified tolerances. The coating partially penetrates the material and partially builds up, but our process ensures final dimensions meet your drawings.
Q: What file formats do you accept?
We work with PDF, DWG, STEP, and IGS formats. If you have a different format, contact us—we'll likely accommodate it.
Q: Do you handle international shipping?
Yes. We offer fast door-to-door delivery optimized for small-batch orders. Duties and shipping can be bundled for your convenience.
