3000 Series 3104 Coil Aluminum Roll H19 Temper For Pop Top Can Body
3104 aluminum plate, also known as 3104 aluminum magnesium manganese alloy, is a 3000 series anti-rust aluminum plate alloy primarily composed of magnesium and manganese elements. This material has become the dominant choice for beverage can bodies due to its optimal balance between strength and formability.
Can Body Applications:
- Initial thickness: 0.250-0.290 mm (rolled down to 0.100-0.110 mm)
- Advanced thinning: ≤0.095 mm (emerging industry trend)
H19 (Extra Hard) - Most Common:
- Tensile yield strength: ≥310 MPa
- Elongation: 2-4% (ensures excellent deep-drawability)
H38 - Alternative for Thinner Designs:
Provides balanced strength and formability for specialized applications.
High Strength and Rigidity: Tensile strength reaches high values in standard testing, ensuring can bodies maintain shape and integrity under internal pressure and external impact during transport.
Excellent Corrosion Resistance: Natural oxidation layer provides superior resistance to acidic and alkaline substances, preventing product deterioration and extending shelf life.
Manufacturing Compatibility: Seamlessly integrates with existing can production lines while delivering consistent surface quality for superior coating adhesion.
Superior Material Properties: Optimal balance between strength and formability maintains structural integrity while allowing ultra-thin can walls.
| Property | 3104 | 3004 |
|---|---|---|
| Strength | Higher (H19 yield ≥310MPa) | Slightly lower (H19 yield ~270-290MPa) |
| Formability | Superior deep-drawing capability (earing <3%) | Better for complex stamping (e.g., end curling) |
| Microstructure | Higher Mn content, controlled texture | More uniform grain structure |
| Typical Thickness | Body: 0.10-0.29mm | End/Lid: 0.20-0.23mm |
| Recyclability | Higher recycled content (>80%) | Slightly lower (~70%) |
Technological & Production Strengths:
- R&D Capabilities: National-level corporate technology center with contributions to industry standards
- Production Scale: Annual capacity exceeding 0.9 million tons of aluminum large-scale rolling mills
- Production Ability: Capable of producing aluminum plate/coil for automotive, railway, marine, and aerospace applications with relevant certifications
