3004 aluminum coil belongs to the 3000 series aluminum alloy, with manganese (Mn) content of approximately 1.2 – 1.5% and aluminum content ≥ 96.8%. This alloy features excellent corrosion resistance, good formability, and higher strength than 3003 Aluminum Coil. It is widely used in roofing, wall panels, transportation, industrial manufacturing, and heat dissipation applications. 3004 Aluminum Coil is easy to process and suitable for rolling, stamping, stretching, and bending, making it an ideal material for high-strength applications.
Description
Features
- Aluminum–manganese alloy (Al–Mn)
Belongs to the 3xxx-series aluminum alloys, with manganese as the primary alloying element and a small amount of magnesium for improved strength.
- Higher mechanical strength than 3003
Provides increased strength while maintaining excellent corrosion resistance, suitable for structural and load-bearing applications.
- Excellent corrosion resistance
Performs well in atmospheric, marine, and industrial environments, suitable for outdoor use.
- Good formability and workability
Soft and ductile, easy to roll, bend, stamp, and deep-draw into thin sheets and complex shapes.
- Good thermal and electrical conductivity
Supports heat dissipation and moderate electrical applications.
- Smooth and uniform surface finish
Ideal for anodizing, painting, coating, embossing, or film lamination.
- Good weldability
Compatible with TIG, MIG, and spot welding, ensuring reliable joints.
- Lightweight material
Low density supports weight reduction in structural, decorative, and functional applications.
