What is Aluminum in CNC Machining
Most CNC parts are actually machined from aluminum alloys rather than pure aluminum. Elements like magnesium, silicon, copper, or zinc are added to adjust strength and other properties. So we offer aluminum machining in a range of alloy grades to meet different requirements for strength, weight, and performance. Aluminum also reacts with oxygen in the air, forming a thin natural oxide layer on its surface. This is why it already had basic corrosion resistance before the post-processing. In additation, with the right machining and finishing approach, we can further tailor the surface and performance of aluminum parts to suit different application requirements.
Choosing the Right Aluminum Grade for Your Part
Machinability, strength, and corrosion resistance of different aluminum materials vary greatly. Below are the grades most commonly used across CNC machining projects. If you are unsure which grade to choose, Erye can help you select the right material for your application.
| Grade | Hardness | Tensile Strength | Key Properties | Common Applications |
|---|---|---|---|---|
| 2024 | ~120 HB | 390–480 MPa | Strong and fatigue-resistant | Wing structures, missile components |
| 5052 | ~60 HB | 210–260 MPa | Excellent corrosion resistance and weldability | Marine hardware, enclosures, fuel tanks |
| 6061 | ~95 HB | 260–310 MPa | Good strength, corrosion resistance, and workability | Mounting brackets, jigs and fixtures, bike frames |
| 7075 | ~150 HB | 500–570 MPa | High-strength, aerospace-grade aluminum | Aircraft wing spars, gears, rock climbing gear |
| MIC 6 | Cast aluminum tooling plate | 220–260 MPa | Excellent flatness and dimensional stability | Tooling plates, jigs, and fixtures |

When you need a material that balances performance, cost, and appearance, aluminum can be an appropriate choice for your CNC machined parts.
Machinability
Cuts fast and cleanly, helping reduce production cycle and per-part cost
Light weight
About a third the density of steel, useful for parts where weight matters
Formability
Handles thin walls and fine detail well without losing dimensional stability
Corrosion resistance
Naturally resist moisture and everyday outdoor exposure
Finishing versatility
Anodizes well, providing a range of color and cosmetic options
Surface Finishing Options for Aluminum Machining
To make sure your aluminum parts perform well and have an attractive appearance, Erye offers several finishing options:

Related FAQs of Aluminum Machining
Why does aluminum sometimes leave a rough or "furry" edge after machining?
This is usually caused by burr formation, which happens more easily with aluminum than harder metals due to its ductility. It's typically addressed with deburring or tumbling as a secondary finishing step.
Can aluminum parts warp during machining?
Thin-walled or asymmetric aluminum parts can experience some distortion from internal stress being released during cutting, especially with softer tempers. This is usually managed by adjusting fixturing, cutting sequence, and toolpaths.
Can aluminum be welded or joined after machining?
Most aluminum grades, such as 6061 and 5052, weld reasonably well. 7075 is more difficult to weld due to its higher strength and susceptibility to cracking, so mechanical fastening is often preferred for that grade.
Can you match a specific color for anodized parts?
Yes, anodizing supports a range of colors. Let us know your target color or provide a reference, like a Pantone code, when you request a quote, and we will confirm what is achievable.
