Description
3003 Aluminum Sheet Manufacturer & Supplier
Hongyuan Aluminum is a China-based aluminum manufacturer supplying 3003 aluminum sheets for industrial fabrication, construction, insulation cladding, chemical equipment and general manufacturing applications.
3003 aluminum is a non-heat-treatable aluminum-manganese alloy belonging to the 3xxx series. It contains approximately 1.0–1.5% manganese and offers higher strength than commercially pure aluminum grades such as 1100 while maintaining good formability and corrosion resistance.
3003 aluminum sheet is widely selected for applications requiring a practical combination of strength, workability, durability and corrosion resistance.
We support customized dimensions, tempers and processing requirements for international B2B customers.

Chemical composition requirements should be checked against the applicable material standard and purchase specifications.
Key Features of 3003 Aluminum Sheet
1. Good Corrosion Resistance
3003 aluminum offers good resistance to corrosion in many atmospheric and industrial environments, making it suitable for general outdoor and industrial applications.
2. Higher Strength Than Pure Aluminum
The addition of manganese increases strength compared with commercially pure aluminum grades such as 1100.
3003 provides a useful balance between strength and formability for general fabrication.
3. Excellent Formability
3003 aluminum sheets can be bent, stamped, rolled and formed into different shapes, particularly when supplied in suitable softer tempers.
4. Good Weldability
3003 aluminum offers good weldability using appropriate welding methods and procedures, making it useful for fabricated components.
5. Non-Heat-Treatable Alloy
3003 aluminum is strengthened primarily through cold working rather than precipitation heat treatment.
3003 Aluminum Sheet Applications
3003 aluminum sheets are commonly used in:
- Sheet metal fabrication and stamped components
- Building cladding and roofing components
- Industrial insulation jacketing
- HVAC ductwork and equipment housings
- Chemical processing equipment
- Storage tanks and fabricated containers
- Decorative and architectural panels
- General industrial forming and fabrication
Final material selection should consider operating conditions, required strength, corrosion exposure and applicable industry standards.
Common Tempers of 3003 Aluminum Sheet
| Temper | Characteristics | Typical Applications |
|---|---|---|
| O | Annealed, soft, excellent formability | Deep drawing and complex forming |
| H12 | Quarter-hard | Light fabrication and bending |
| H14 | Half-hard | General sheet metal fabrication |
| H16 | Three-quarter-hard | Components requiring increased rigidity |
| H18 | Full-hard | Relatively rigid sheet components |
| H24 | Strain-hardened and partially annealed, half-hard | Insulation jacketing and general fabrication |
The appropriate temper depends on thickness, forming requirements and the specified mechanical properties.
3003 Aluminum Sheet vs 1100 Aluminum Sheet
3003 and 1100 aluminum sheets are both non-heat-treatable alloys with good corrosion resistance and formability.
However, 3003 contains manganese and provides higher strength than 1100.
| Property | 3003 Aluminum Sheet | 1100 Aluminum Sheet |
|---|---|---|
| Alloy Series | 3xxx | 1xxx |
| Main Alloying Element | Manganese | Commercially pure aluminum |
| Strength | Higher | Lower |
| Formability | Good to excellent | Excellent |
| Corrosion Resistance | Good | Good |
| Typical Applications | Cladding, insulation, industrial fabrication | Stamping, forming, general fabrication |
3003 is often preferred when additional strength is required while maintaining good formability.
1100 may be preferred when high aluminum purity and maximum formability are more important.
