Why Choose Aluminum for CNC Machining?
Aluminum is the most popular material for CNC machining due to its excellent machinability, light weight, and corrosion resistance. With a strength-to-weight ratio superior to steel, aluminum parts are essential in aerospace, automotive, and consumer electronics industries.
Common Aluminum Grades
| Grade | Characteristics | Best For |
|---|---|---|
| 6061-T6 | Good strength, weldable | Structural parts |
| 7075-T6 | High strength | Aerospace components |
| 5052-H32 | Excellent corrosion resistance | Marine applications |
| 2024-T3 | High fatigue resistance | Aircraft structures |
Key Benefits
- Lightweight: 1/3 the weight of steel
- Corrosion Resistant: Natural oxide layer protection
- Excellent Machinability: High cutting speeds possible
- Recyclable: 100% recyclable material
Cost Factors
CNC aluminum machining costs depend on part complexity, tolerances required, surface finish specifications, and order volume. Typical prototypes range from $50-500, while production runs benefit from economies of scale.
