What Does 3003 H14 Mean?
3003 H14 aluminum is made with a manganese-based alloy that offers excellent corrosion resistance and good mechanical properties.
- 3003 refers to the alloy, with about 1.2% manganese.
- H14 indicates the strain-hardened temper to about half-hard.
This temper provides a balance of strength and workability, making it ideal for bending, spinning, and forming operations.
What Is the Difference Between 3003 H14 and 6061 T6?
| Feature | 3003 H14 | 6061 T6 |
|---|---|---|
| Alloy Type | Non-heat treatable | Heat treatable |
| Strength | Moderate | High |
| Corrosion Resistance | Excellent | Very Good |
| Workability | Excellent | Good |
| Weldability | Good | Excellent |
While 6061 T6 aluminum is stronger and more suitable for structural applications, 3003 H14 is more cost-effective and easier to form, making it perfect for sheet metal work.
What Is the Difference Between 3003 H14 and 5052 Aluminum?
| Feature | 3003 H14 | 5052 H32 |
|---|---|---|
| Main Alloying Element | Manganese | Magnesium |
| Strength | Moderate | Higher |
| Corrosion Resistance | Excellent | Excellent |
| Workability | Very Good | Good |
| Marine Use | Not Recommended | Suitable |
5052 aluminum is stronger and more suitable for marine environments, while 3003 aluminum offers better workability and is often used in architectural and decorative applications.
