What are Aluminum CNC Machining Parts?
Aluminium CNC machining parts are custom components created from aluminum alloys using CNC (computer numerical control) machines that shape the material with incredible precision. This process achieves tight tolerances and high-quality finishes that meet the specific requirements of demanding industries like automotive, aerospace, medical devices, and electronics.
Whether you’re working with aluminum 6061, aluminum 7075, or other popular aluminum alloys, CNC machining delivers parts with excellent machinability and an outstanding strength-to-weight ratio. From sheet metal components to complex aluminum parts requiring multiple machining operations, we handle various processes using cutting tools designed to meet the highest industry standards.
How do You Choose the Right Aluminum Alloy?
Choosing the right aluminum alloy comes down to what your project actually needs. Different alloys bring varying levels of strength, resistance to corrosion, and formability to the table, so picking the wrong one can compromise performance or cost you more than necessary. Weldability and electrical conductivity also play a role.
| Alliage d'aluminium | Propriétés principales | Utilisations courantes |
|---|---|---|
| 6061 | Great machinability, medium strength, good corrosion resistance | Aerospace secondary parts, automotive secondary components, marine applications |
| 7075 | High strength, excellent fatigue resistance, tough | Aerospace, high-stress structural parts |
| 2024 | Excellent fatigue resistance, lower corrosion resistance | Aerospace, aircraft components |
| 5052 | Corrosion resistant, moderate strength | Marine applications, fuel tanks |
| MIC-6 | Stress-free, excellent machinability | Tooling, precision fixtures |
Each aluminum alloy has unique advantages for CNC machining that match the specific mechanical properties required by industries like aerospace, automotive, and marine. The trick is understanding what your application demands and selecting the alloy that delivers those properties without paying for features you don’t need.
What is the CNC Machining Process for Aluminum?
The CNC machining process for aluminum parts involves several critical steps to create precise components:
- Design & Programming: Your CAD design is converted into a machine-readable format, ensuring all aspects of the part are captured in the CNC machining program.
- Sélection des matériaux: We choose the aluminum alloy best suited to your part’s requirements, whether aluminum 6061, 7075, or another high-performance aluminum alloy.
- Usinage: Utilisation Fraisage CNC ou Tournage CNC, the aluminum is cut into the desired shape with tight tolerances (±0.05 mm or better). This is achieved using advanced cutting tools that are optimized for aluminum machining.
- Finition: After machining, we apply various finishing processes like anodizing, chem-film, or powder coating to enhance corrosion resistance, durability, and appearance.
- Inspection et contrôle de la qualité: Using CMM (coordinate measuring machine) inspections and SPC (statistical process control), we ensure every part meets your tolerance requirements.
This process ensures that every CNC machined aluminum part has consistent quality, from prototypes to high-volume production.
What is the Machining Tolerance for Aluminum?
Aluminum CNC machining can achieve high levels of precision, making it ideal for aerospace parts, automotive applications, and other industries that demand tight tolerances. The typical tolerances for CNC aluminum machining are:
- ±0.10 to 0.05 mm for standard parts
- ±0,01 mm for high-precision parts
- ±0,005 mm for ultra-precise applications
These tolerances are achievable with CNC milling and CNC turning processes, and we ensure that all parts are CNC machined to meet the required specifications.
What are the Common Applications for Aluminum CNC Machining?
Aluminum CNC machined parts are used across a broad spectrum of industries. Some common applications include:
- Aérospatiale: Lightweight, high-strength components like aircraft parts, brackets, and engine housings.
- Automobile: Precision parts such as automotive parts, engine components, and bicycle frames that require a high strength-to-weight ratio.
- Médical: Components like surgical instruments, housings for medical devices, and other critical parts requiring high precision.
- Marine: Parts exposed to harsh environmental conditions, where corrosion-resistant properties are essential.
- Électronique: CNC milling for aluminum parts that serve as heat sinks, enclosures, and connectors.
The excellent machinability and corrosion resistance of aluminum make it the material of choice for machined aluminum parts used in various industries.

Aluminum CNC Machining Parts FAQs
The cost of CNC machining aluminum depends on the complexity of the design, the aluminum alloy used, and the finishing process. Simple parts with 6061 aluminum and standard tolerances are more affordable, while parts requiring 7075 or tight tolerances can increase the cost. Contact us for an instant quote based on your design.
Some materials, such as ceramics, glass, and certain composite materials, are more difficult to machine due to their brittleness or hardness. Titanium and stainless steel are machinable, but require more specialized tools and techniques than aluminum.
Aluminum is relatively easy to machine compared to other metals. Its excellent machinability, low hardness, and good formability make it a popular choice for CNC machining. However, certain alloys like 7075 may require specialized tools due to their higher strength.
