Product Details
3003 H14 aluminum sheet is a widely used non-heat-treatable aluminum-manganese alloy in a strain-hardened condition. The “H14” temper indicates that the material has been partially hardened, giving it a balance between strength and formability.
It is one of the most common aluminum sheet grades for general fabrication, packaging, and architectural applications.
Chemical Composition (Typical)
3003 aluminum belongs to the Al-Mn alloy series, with manganese as the main strengthening element.
| Element | Content (%) | Function |
|---|---|---|
| Manganese (Mn) | 1.0 – 1.5 | Improves strength and corrosion resistance |
| Copper (Cu) | 0.05 – 0.20 | Slight strength enhancement |
| Iron (Fe) | ≤ 0.70 | Impurity control |
| Silicon (Si) | ≤ 0.60 | Improves casting and processing stability |
| Aluminum (Al) | Balance | Base metal |
Mechanical Properties (H14 Condition)
- Medium strength among non-heat-treatable alloys
- Good formability in H14 temper condition
- Excellent corrosion resistance in atmospheric environments
- Good weldability and cold working performance
Typical characteristics:
- Higher strength than 1100 series aluminum
- Better forming ability than harder tempers (H18, H24)
- Stable performance in indoor and outdoor environments
Key Performance Features
1. Good Corrosion Resistance
3003 aluminum performs well in:
- Atmospheric environments
- Moisture exposure
- Mild chemical conditions
It forms a natural oxide layer that protects the surface from corrosion.
2. Excellent Formability
- Suitable for bending, rolling, and stamping
- Commonly used in complex shaping processes
- Maintains surface integrity after forming
3. Moderate Strength
- Stronger than pure aluminum (1100 series)
- Suitable for lightweight structural and decorative use
- Not designed for heavy load-bearing applications
4. Good Weldability
- Compatible with common welding methods
- Stable joint performance
- Widely used in fabricated structures
Common Applications of 3003 H14 Aluminum Sheet
1. Roofing and Cladding Systems
- Building roof panels
- Wall cladding sheets
- Decorative exterior panels
2. HVAC and Insulation Systems
- Air conditioning ducting
- Thermal insulation covers
- Ventilation systems
3. Packaging Industry
- Food and beverage containers
- Storage tanks for non-corrosive materials
- Light industrial packaging components
4. Transportation and Automotive Use
- Lightweight vehicle panels
- Interior decorative components
- Non-structural body parts
5. General Fabrication
- Metal enclosures
- Appliance components
- Light industrial equipment housings
