The difference between 3104 aluminum coil and 3004 aluminum coil

Both 3104 and 3004 are commonly used aluminum alloy coils in various applications, but there are some differences in their chemical composition and properties. The following is a comparison of 3104 aluminum coils and 3004 aluminum coils:

chemical composition:

3104 aluminum coil:
Aluminum (Al): 95.7%
Magnesium (Mg): 0.8-1.3%
Manganese (Mn): 0.8-1.3%
Zinc (Zn): 0.25%
Other elements: Trace other elements
3004 aluminum coil:
Aluminum (Al): 95.8-98.2%
Magnesium (Mg): 0.8-1.3%
Manganese (Mn): 1.0-1.5%
Iron (Fe): 0.7%
Other elements: Trace other elements
Manganese content:

One of the main differences between these two alloys is the manganese content. Compared with 3104 aluminum, 3004 aluminum has a slightly higher manganese content. This difference affects the mechanical properties and formability of the alloy.


3004 aluminum is known for its excellent formability. It is typically used in applications that require deep drawing or forming, such as beverage cans.
3104 aluminum also has good formability, but may have slightly different properties in terms of stretchability and deformation behavior due to its lower manganese content.
Corrosion resistance:

Both alloys have good corrosion resistance. They are suitable for applications where exposure to moisture and environmental factors is a consideration.


3104 aluminum coil:
Commonly used in the production of beverage can lids, shallow-drawn cans and automotive parts.
3004 aluminum coil:
Widely used in the manufacture of beverage cans (tanks) as it provides excellent formability and corrosion resistance for this application.


Both alloys have similar strength properties, but a slight difference in manganese content affects their mechanical properties. Specific strength values may depend on factors such as tempering and processing.


Both alloys can be welded using common methods such as TIG or MIG welding and exhibit good weldability.

Although 3104 and 3004 aluminum coils have some similarities in their aluminum-magnesium-manganese alloy composition, they differ in their manganese content and are generally used in different applications. Due to its excellent formability, 3004 is often the material of choice for beverage can bodies, while 3104 is used in applications such as can ends and automotive parts. The choice between them depends on the specific requirements of the application.
