Aluminum Alloys 3004 and 8011
Alloy Composition Technical Focus
Alloy 3004:
- Primary Alloying Elements: Manganese (Mn), Magnesium (Mg), and small proportions of Copper (Cu).
- Application-Driven Specifications: Specifically, 3004 is established as a “work-hardenable” alloy that showcases high machinability due to the work-hardening process, further enhanced through annealing treatments.
Alloy 8011:
- Primary Alloying Elements: Iron (Fe), with intentional minimal percentages of Copper and rare elements like Silicon.
- Common Applications: 8011 is largely known for its suitability in myriad wrapping applications, primarily due to its insulating properties and commendable mechanical characteristics.
Chemical Composition Table
| Alloy | Aluminum (Al) | Manganese (Mn) | Magnesium (Mg) | Copper (Cu) | Iron (Fe) | Silicon (Si) |
|---|---|---|---|---|---|---|
| 3004 | Bal. | 1.0-1.5% | 0.8-1.5% | 0.05% max | 0.7% max | 0.5% max |
| 8011 | Bal. | N/A | N/A | 0.2% max | 0.6-1.0% | 0.3% max |
Alloy Tempering and Mechanical Properties
