Product Details
3003-O aluminum sheet is a fully annealed aluminum-manganese alloy sheet designed for applications requiring excellent formability and deep drawing performance. Compared with hardened 3003 tempers, the O condition provides higher ductility, lower forming resistance, and better resistance to cracking during stamping operations.
Because of its balance between corrosion resistance, weldability, and deep drawing ability, 3003-O aluminum sheet is widely used for cookware, lighting reflectors, enclosures, automotive parts, and formed industrial components.
What Is 3003-O Aluminum Sheet?
3003 aluminum belongs to the Al-Mn alloy family. Manganese improves strength compared with pure aluminum while maintaining good corrosion resistance and fabrication performance.
The “O” temper indicates that the material has been fully annealed. During annealing, internal stress is removed and the aluminum becomes softer, allowing deeper forming operations.
3003 = Aluminum-manganese alloy with improved strength over pure aluminum
O = Fully annealed condition for maximum formability
3003-O Aluminum Chemical Composition
The manganese content gives 3003-O better strength than 1100 aluminum while keeping excellent corrosion resistance and welding performance.
| Element | Typical Content |
|---|---|
| Aluminum (Al) | Balance |
| Manganese (Mn) | 1.0-1.5% |
| Copper (Cu) | 0.05-0.20% |
| Other Elements | Controlled trace elements |
3003-O Mechanical Properties
The fully annealed condition provides the highest ductility among common 3003 tempers. It is especially suitable for parts requiring stretching, bending, and deep drawing.
| Property | Typical Value |
|---|---|
| Tensile Strength | Approximately 95-135 MPa |
| Elongation | Around 30% |
| Temper | O (Fully Annealed) |
| Density | Approximately 2.73 g/cm³ |
Why 3003-O Is Selected for Deep Drawing
Deep drawing requires aluminum with high elongation and low forming resistance. The soft annealed condition allows the material to flow during stamping without excessive cracking or tearing.
| Advantage | Manufacturing Benefit |
|---|---|
| High Ductility | Reduces cracking during forming |
| Low Hardness | Allows complex shapes |
| Stable Forming | Suitable for repeated stamping |
3003-O vs 3003-H14 Aluminum Sheet
The alloy is the same, but the temper changes the mechanical behavior. The selection depends on whether forming ability or structural strength is more important.
| Comparison | 3003-O | 3003-H14 |
|---|---|---|
| Condition | Fully annealed | Strain hardened |
| Formability | Excellent | Moderate |
| Strength | Lower | Higher |
| Typical Use | Deep drawing and stamping | Panels and general structures |
3003-O Deep Drawing Process Considerations
Although 3003-O has excellent forming ability, production quality still depends on tooling design and process control.
- Die design: Proper clearance helps prevent tearing and wrinkles.
- Lubrication: Suitable forming lubricants reduce friction and surface damage.
- Springback control: Tool compensation may be required for final dimensions.
- Material testing: Trial forming is recommended for complex parts.
Applications of 3003-O Aluminum Sheet
| Application | Reason for Selection |
|---|---|
| Cookware | Good forming and corrosion resistance |
| Lighting Reflectors | Smooth surface and easy shaping |
| Equipment Enclosures | Lightweight and corrosion resistant |
| Automotive Parts | Suitable for formed components |
| Instrument Housings | Good appearance and fabrication performance |
