3000 Series 3104 Alloy Coil Aluminum Used For Pop-top Can Body
3104 aluminum plate can be called 3104 aluminum magnesium manganese
plate alloy. It is
a 3 series anti-rust aluminum plate alloy. Its main alloy components
are magnesium and ma
-nganese.
3104 is the dominant material for beverage cans due to its optimal
strength-formability balance.
Standard Thickness
Can Body:
Initial thickness: 0.250–0.290 mm (rolled down to 0.100–0.110 mm)
Advanced thinning: ≤0.095 mm (emerging trend)
Typical Tempers
H19 (Extra Hard) (Most common)
Tensile yield strength: ≥310 MPa
Elongation: 2–4% (ensures deep-drawability)
H38 (Alternative for thinner designs)
Balanced strength and formability
Advantages of 3104 H19 Aluminum Coil
1 High Strength and Rigidity
The tensile strength of 3104 H19 aluminum coil can reach high
values in standard tests. This
characteristic ensures that can bodies maintain their shape and integrity under
internal pressure
(such as gas pressure) and external impact (such as vibrations during transport).
2 Good Corrosion Resistance
The natural oxidation layer of aluminum gives 3104 H19 materials
excellent corrosion resistance
when in contact with liquids, especially acidic and alkaline substances.
This prevents food or bever
-ages from deteriorating, thereby extending their shelf life.
3 Excellent Manufacturing Compatibility
Seamlessly integrates with existing can production lines.
Delivers consistent surface quality for superior coating adhesion.
4 Superior Material Properties
Offers an optimal balance between strength and formability
Maintains structural integrity while allowing ultra-thin can walls
Key Performance Comparison
| 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%) |
