| Aluminum Grade | Yield Strength | Machinability | Corrosion Res. | Best For (Typical Applications) |
|---|---|---|---|---|
| 6061-T6 | 276 MPa | Good | Good | General-purpose parts, fixtures, automotive frames |
| 7075-T6 | 503 MPa | Excellent | Fair | Aerospace, high-stress gears, military components |
| 5052-H32 | 193 MPa | Fair | Excellent | Marine environments, electronic enclosures, panels |
| 2024-T3 | 345 MPa | Excellent | Poor | Fatigue-resistant parts, aircraft structural fittings |
| 6082-T6 | 260 MPa | Good | Excellent | European standard alternative to 6061, heavy stress |
| Machining Level | Equipment Type | General Dimensional Tolerance | Hole Tolerance | Surface Roughness (Ra) |
|---|---|---|---|---|
| Standard Precision | 3-Axis CNC / Lathe | ±0.10 – ±0.20 mm | ±0.10 – ±0.15 mm | 3.2 – 6.3 μm |
| Precision Level | 4-Axis / 5-Axis / Mill-Turn | ±0.025 – ±0.05 mm | ±0.02 – ±0.05 mm | 1.6 – 3.2 μm |
| High Precision | 5-Axis Simultaneous / 9-Axis | ±0.005 – ±0.01 mm | ±0.005 – ±0.01 mm | 0.4 – 1.6 μm |
| Ultra Precision | Ultra-Precision / EDM / Nano Machining | ±0.001 – ±0.005 mm | ±0.002 – ±0.005 mm | 0.1 – 0.4 μm |
| Design Feature | Optimization Guideline |
|---|---|
| Inner Corner Radii | Ensure your inner radii are 0.020″-0.050″ larger than standard drill bits. Maintain a diameter-to-depth ratio of 1:4 to achieve optimal machining efficiency. |
| Base / Floor Fillets | Design base fillets smaller than vertical corner radii. This allows the same cutting tool to clear bottom material seamlessly, saving you setup time. |
| Undercut Dimensions | Utilize standard tooling sizes for all undercuts. Position them away from tight corners to guarantee easy access for the cutting tool. |
| Threaded Hole Clearance | Add extra drill depth beyond the required threaded section. This clearance allows the tap to create fully formed threads securely. |
| Part Complexity | Minimize non-functional intricate cuts to lower your total manufacturing costs. Focus on essential features that balance mechanical performance and aesthetics perfectly. |
