Characteristics
| Feature | Description |
| Strength | Has higher strength compared to 3003 alloy. |
| Workability | Exhibits excellent workability in the annealed state. |
| Heat Treatment | Cannot be strengthened through heat treatment. |
| Anodizing | Suffers from severe anodizing color differences, thus is generally not suitable for anodizing processing. |
Due to the presence of magnesium in 3004 alloy, the main processing method is hot - rolling. This technique helps in achieving the desired properties and form of the alloy for different applications.
