The overall performance of 3104 aluminum sheet is significantly superior to that of 3003 and 3105 aluminum sheets, offering an excellent combination of lightweight properties, safety, and cost-effectiveness.
3104 aluminum sheet is a 3xxx series Al-Mn-Mg anti-rust wrought aluminum alloy. It is non-heat-treatable and cannot be strengthened by heat treatment. Its key characteristics include high strength, exceptional deep-drawing performance, excellent corrosion resistance, and food-grade safety.
With overall performance significantly superior to 3003 and 3105 aluminum sheets, 3104 aluminum sheet is a benchmark material for beverage cans, food packaging, automotive fuel tanks, and high-end architectural decoration. It combines lightweight properties, safety, and cost efficiency.
O Temper (Annealed): Offers the highest ductility and is suitable for deep drawing and bending, such as beverage can bodies and food containers.
H14 / H24 Temper (Semi-Hard): Provides a balanced combination of strength and formability. Suitable for architectural panels, shutters, and lamp holders.
H19 Temper (Full-Hard): Offers the highest strength and is suitable for beverage can ends, high-pressure sealing components, and thin-wall structural parts.

1. Excellent Deep-Drawing Formability
3104 aluminum sheet demonstrates exceptional stability during the draw-and-wall-ironing process. It can be thinned without cracking, enabling it to withstand multiple wall-ironing stages. This makes it a preferred material for lightweight metal containers.
2. High Structural Strength
Compared with 3003 aluminum sheet, 3104 offers higher hardness and mechanical strength. Even after lightweight thinning, it maintains sufficient rigidity to ensure the structural stability of the finished product.
3. Outstanding Corrosion and Rust Resistance
Due to its manganese content, 3104 aluminum sheet provides strong protection in demanding environments, including acidic beverage environments and corrosive atmospheric conditions. It offers high safety and reliable durability.
4. Excellent Surface-Treatment Performance
3104 aluminum sheet has a dense and flat surface, making it highly suitable for color coating, anodizing, and printing. It provides excellent paint and color adhesion.
5. Recyclable and Environmentally Friendly
Aluminum is an environmentally friendly and fully recyclable material. 3104 aluminum sheet is widely used in sustainable packaging solutions.
Metal Packaging — Core Application
3104 is a globally recognized standard material for beverage can bodies. It is also used for food aerosol cans, chemical cans, and other packaging containers.
New Energy Industry
Thanks to its excellent stamping stability, it is widely used in lithium battery housings, explosion-proof valves, and battery-module components.
Architecture and Curtain Walls
Used as substrate material for high-grade color-coated aluminum coils, aluminum-alloy shutters, roofing systems, and ceilings.
Lighting and Electronics
Suitable for precision lamp-cap materials, LCD display back panels, and stamped electronic components.
To ensure product quality, 3104 aluminum sheet can undergo the following inspections and tests:
Visual and dimensional inspection
Mechanical testing, including tensile strength, elongation, and reduction of area
Ultrasonic testing
Chemical composition analysis
Hardness testing
Pitting corrosion resistance testing
Penetrant testing
Intergranular corrosion testing
Impact testing
