Process Fit
When to Choose Aluminum CNC Machining
Aluminum CNC machining is often selected when a part needs a strong but lightweight structure, good machinability, corrosion resistance, thermal conductivity, electrical performance or anodized appearance. It is widely used for housings, brackets, heat sinks, fixtures, robotics components, electronic enclosures, UAV parts and production-grade prototypes.
Very large bent panels may be better suited for sheet metal fabrication. Early visual concept models may be faster with 3D printing service. Very high-volume cast-style aluminum geometry may require die casting service.
Choose aluminum CNC when
You need lightweight metal parts, housings, brackets, heat sinks, fixtures or anodized customer-facing components.
Review alloy before quoting
6061, 7075, 6063, 5052 and cast aluminum serve different strength, finish and manufacturing needs.
Plan thin walls carefully
Thin aluminum housings require wall thickness, clamping, deformation and finishing review.
Define cosmetic surfaces
Visible surfaces, anodizing color, bead blasting texture and packaging protection should be specified early.
Alloy Selection
Aluminum Alloy Selection for CNC Machined Parts
The best aluminum alloy depends on the purpose of the part. Baosheng reviews strength, machinability, corrosion resistance, anodizing, cost and availability before quoting.
| Aluminum Alloy | Typical Use | Notes |
|---|---|---|
| Aluminum 6061 | Housings, brackets, fixtures, plates and general machined parts. | Balanced strength, machinability, corrosion resistance and anodizing compatibility. |
| Aluminum 7075 | UAV parts, robotics components, high-strength brackets and structural parts. | Higher strength than 6061, often used when lightweight strength matters. |
| Aluminum 6063 | Heat sinks, extrusion-related components and appearance parts. | Good for thermal and appearance-focused parts, commonly used with anodizing. |
| Aluminum 5052 | Sheet metal parts, panels, brackets and covers. | Often better suited for sheet metal fabrication than heavy CNC machining. |
| Aluminum 2024 | Aerospace-style structural components. | High strength, but corrosion resistance and finishing should be reviewed carefully. |
| Cast Aluminum | Die-cast or cast parts needing secondary machining. | Useful when geometry is casting-based and quantities justify tooling. |

Finishing
Surface Finishing for Aluminum CNC Parts
Aluminum surface finishing should be reviewed before machining because anodizing, bead blasting, polishing and coating can affect appearance, dimensions, threads, sharp edges and cosmetic surfaces. For customer-facing aluminum parts, color, texture, masking requirements and packaging protection should be defined before production.
As-Machined
Functional aluminum parts where tool marks are acceptable.
Bead Blasting
Uniform matte surface before anodizing or cosmetic review.
Clear Anodizing
Corrosion resistance and natural aluminum appearance.
Black Anodizing
Electronics housings, brackets and customer-facing parts.

Design Tips for Aluminum CNC Machined Parts
Good aluminum part design balances alloy selection, wall thickness, realistic internal radii, thread strength, finishing requirements and inspection notes.
- Use 6061 for general parts, 7075 for higher strength, 6063 for heat sinks or appearance parts, and 5052 for sheet metal-style components.
- Avoid overly thin walls unless necessary. Thin aluminum walls may deform during machining or finishing.
- Add realistic internal radii where possible to improve machinability and reduce cost.
- Deep narrow pockets increase machining time, tool deflection and cost.
- Define thread depth clearly and consider inserts if repeated assembly or thread strength is important.
- Review color, masking, surface texture and dimensional impact before anodizing.
- Mark visible surfaces, flat mating surfaces and heat transfer surfaces clearly on the drawing.
- Tighten only dimensions that affect fit, function or assembly.
For broader pricing factors, review CNC machining cost.

Aluminum CNC Machining FAQs
What is aluminum CNC machining?
Aluminum CNC machining is the process of removing material from aluminum stock using CNC milling, turning or multi-axis machining to produce custom aluminum parts with defined geometry, tolerances and surface finish.
Which aluminum alloy is best for CNC machining?
6061 aluminum is commonly used for general CNC machined parts because it balances machinability, strength, corrosion resistance and anodizing compatibility. 7075 is used when higher strength is required, while 6063 is often used for heat sinks and appearance parts.
Can you machine 6061 aluminum parts?
Yes. Baosheng supports 6061 aluminum CNC machining for housings, brackets, fixtures, plates, prototypes, low-volume parts and production components.

Yes. 7075 aluminum can be reviewed for high-strength lightweight parts such as UAV brackets, robotic components and structural aluminum parts.
Can aluminum CNC parts be anodized?
Yes. Aluminum CNC parts can be finished with clear anodizing, black anodizing, bead blasting before anodizing and other surface treatments depending on alloy and application.
Can anodizing affect dimensions?
Yes. Anodizing can affect surfaces, edges, threads and critical dimensions. Finishing requirements should be reviewed before machining, especially for tight tolerance or threaded aluminum parts.
Can you machine thin-wall aluminum housings?
