Matte Anodized Aluminum Parts – Precision CNC Machining with Premium Surface Finish
Shenzhen Ruiyihang Technology makes Matte Anodized Aluminum parts with tight tolerances and great surface performance. We have been specialising in custom CNC machining with combined anodising services since 2008. Our method is based on engineering, and it guarantees a tolerance of ±0.02 mm (±0.01 mm for important features), a 7-day sample turnaround (as little as 3 days for simple parts), and 100% custom production. We offer direct technical support—no middlemen—from engineers with an average of 15+ years of experience to make sure your ideas are the best they can be for performance and manufacturability.
What Is Matte Anodized Aluminum?
Our product makes a smooth, non-reflective surface that makes things look better and work better.
Type II anodising, bead blasting, and CNC precise cutting are all used together in this process.
As a result? Finished parts that don't reflect much light, are more resistant to rust, and look good.
You get accurate measurements along with a surface that lasts and looks great.
It's perfect when you need both performance and good looks.
Why Choose Matte Anodized Aluminum for Your Project?
Superior Surface Properties
At the same time that it builds up on top, the anodising layer grows into the aluminium base.
This makes an oxide film that is 5–25 μm thick and part of the material, not just on the surface.
Your parts will be less likely to rust and have a harder finish.
The matte material covers up small flaws and gives the item a smooth, professional look.
Perfect for Visible Components
Matte Anodised Aluminium is the way to go when looks are important.
The finish is not shiny, so it doesn't show dirt or glare.
It works great for market goods, robotics parts, coffee machine housings, and computer enclosures.
You get performance that works well and looks good, which will please your customers.
Precision Meets Durability
To meet your particular needs, we make aluminium alloys such as 6061-T6, 6063, and 7075-T6.
We make the surface rough (Ra 1.6–3.2 μm) before anodising.
To account for the growth of oxide layers, our experts figure out cutting margins.
This makes sure that the end parts stay the exact size that your application needs.
Our Manufacturing Process
Step 1: Engineering Review
You and our experts look over your plans together.
We talk about choosing the right material, limits, and surface needs.
This early cooperation cuts down on mistakes and speeds up the output process.
Step 2: Precision CNC Machining
We use CNC machines with multiple axes to make complicated shapes with very tight limits.
Parts that are ready to be finished are made by milling, turning, and cutting.
During cutting, critical measurements are kept an eye on.
Step 3: Surface Preparation
Bead blasting is used to give parts a uniform matte finish.
This step is necessary to get that surface shine that doesn't reflect light.
Step 4: Anodizing Treatment
Based on your needs, either Type II (normal) or Type III (hard) anodising is used.
You can choose from Natural Silver, Black, Gold, or your own colour.
The coating's thickness is controlled and checked to make sure it stays the same.
Step 5: Quality Inspection
We check for even colour, covering thickness, and accurate measurements.
You can choose between a 100% inspection or a sampling exam of Matte Anodized Aluminum, based on your needs.

FAQ
Q: What is matte anodizing?
Matte anodising improves corrosion resistance and aluminium surface hardness while creating a homogeneous non-reflective surface. This is done using bead blasting and Type II anodising.
Q: Can CNC aluminium parts be matte anodised?
Matte anodising CNC machined, turned, or drilled aluminium parts does not effect dimensional accuracy. We calculate machining allowances to preserve your tolerances after anodising.
Q: How does matte anodising vary from transparent or coloured?
Matte anodising uses bead blasting to make the surface non-reflective. Clear, glossy anodising preserves aluminum's inherent colour. Coloured anodising adds beautiful dyes. Typ III hard anodising hardens surfaces for wear resistance.
Q: What tolerance can you hold after matte anodizing?
Typically, we maintain ±0.02 mm for general characteristics and ±0.01 mm for important dimensions. We account for oxide layer formation during machining to guarantee items fit your standards.
Q: How long does production take?
Simple components may be made in 3 days, whereas samples require 7 days. Production time depends on complexity and quantity. Our deadlines are obvious after studying your designs.
