Aluminum CNC Machined Parts (China Manufacturer)
Aluminum is one of the most popular materials for CNC machining because it combines low weight, high strength, excellent machinability, and corrosion resistance. At Davantech, we manufacture custom aluminum CNC machined parts for international customers who need reliable tolerances, clean finishing, and stable quality—whether you need one prototype or full production batches.
✅ ISO 9001:2015 certified
✅ CNC milling + turning
✅ Aluminum 6061 / 7075 / 5052 / 7050 and more
✅ Optional anodizing, powder coating, polishing
✅ Fast quotation within 24 hours
Why Choose Aluminum for CNC Machining?
Aluminum is often the best choice when your part needs a strong structure without adding unnecessary weight. It is widely used for mechanical components, enclosures, brackets, frames, and heat management parts.
Key Advantages of Aluminum
- Lightweight with high strength-to-weight ratio
Ideal for aerospace, robotics, automotive parts, and portable devices. - Excellent machinability
Aluminum cuts cleanly and efficiently, reducing cycle time and production cost. - Good thermal conductivity
Perfect for heatsinks, LED parts, and electronic housings. - Natural corrosion resistance
Does not rust and performs well in demanding environments. - 100% recyclable
A sustainable option for industrial manufacturing.
Common Aluminum Grades We Machine
We support many aluminum alloys based on your strength, corrosion, and finishing requirements.
Typical grades include:
- Aluminum 6061 – most common, great balance of strength + machinability
- Aluminum 7075 – high strength for structural and aerospace applications
- Aluminum 5052 – strong corrosion resistance, good for sheet-based parts
- Aluminum 7050 / 2024 / MIC-6 – available upon request

Our Aluminum CNC Machining Process
We make ordering aluminum CNC parts simple and predictable.
Step 1 — CAD Review & DFM Optimization
Upload your CAD file or drawings (STEP / IGES / PDF).
Our engineers review your design and optimize it for manufacturability.
Step 2 — Material Selection
Choose from common grades like 6061 or 7075, or request a specific alloy.
Step 3 — Precision CNC Machining
We machine your parts using stable cutting parameters for clean surfaces and consistent dimensions.
Step 4 — Quality Inspection
Each batch is checked using:
- calipers & micrometers
- height gauges
- CMM measurement (when required)
Step 5 — Surface Finishing (Optional)
Choose finishes for durability, corrosion resistance, or cosmetic appearance.
Step 6 — Packing & Fast Delivery
Export packaging and fast shipping options are available.
Many orders can be delivered in as little as 5 working days depending on complexity and quantity.
Surface Finishing for Aluminum CNC Parts
Improve both appearance and performance with professional surface treatments:
Available Finishing Options
- Anodizing (clear or color) – corrosion resistance + clean look
- Powder coating – durable and customizable coatings
- Wet painting – wide color selection and textures
- Polishing – smooth cosmetic finish
- Sandblasting – matte surface and consistent texture
If you need a specific finish standard (color code, thickness, masking areas), we can support that too.

FAQ — Aluminum CNC Machining
What is the best aluminum grade for CNC machining?
Aluminum 6061 is the most common choice because it offers excellent machinability, good strength, and consistent surface finishing. For higher strength applications, Aluminum 7075 is often selected.
Can you CNC machine aluminum prototypes and small batches?
Yes. Davantech supports 1-piece prototypes, small batches, and full production. We can also provide DFM feedback to improve cost, lead time, and manufacturability.
What surface finish is best for aluminum parts?
For corrosion resistance and a clean professional look, anodizing is a top choice (clear or color). For durable paint-like finishes and a wide color range, powder coating is also popular.
How fast can you deliver aluminum CNC machined parts?
Lead time depends on part complexity, quantity, and finishing. Many orders can be delivered in 5–10 working days after drawing approval and material confirmation.
Do you provide inspection reports?
Yes. We can provide measurement reports (critical dimensions) and CMM inspection when required by your drawing or quality plan.
