Advantages of Aluminum Blocks
Aluminum blocks offer a unique combination of benefits, making them ideal for precision engineering and heavy-duty applications:
Lightweight: Around one-third the weight of steel
Excellent Machinability: Suitable for CNC operations
Corrosion Resistance: Particularly 6061, 5083, and 6082
High Strength-to-Weight Ratio: Especially 7075 and 2024
Thermal Conductivity: Great for heat sink applications
Recyclability: 100% recyclable with low environmental impact
Aluminum Block vs. Other Metals
| Property | Aluminum (6061/7075) | Steel (Mild/SS) | Copper |
| Density (g/cm3) | ~2.7 | ~7.8 | ~8.9 |
| Corrosion Resistance | High (6061) | Low–Medium | Medium |
| Machinability | Excellent | Moderate | Good |
| Cost | Lower than copper | Similar/lower | High |
| Recyclability | Excellent | Good | Excellent |
Aluminum is often chosen over steel or copper for weight-sensitive or corrosion-prone environments.
