Description
Features
- Aluminum–manganese alloy (Al–Mn)
Belongs to the 3xxx-series aluminum alloys, with manganese as the main alloying element, offering improved strength over pure aluminum.
- Medium mechanical strength
Stronger than 1000-series aluminum, suitable for general structural and load-bearing applications.
- Excellent corrosion resistance
Provides reliable resistance to atmospheric, marine, and industrial environments.
- Good formability and workability
Soft and ductile, easy to roll, bend, stamp, and deep-draw, suitable for thin-gauge processing.
- Good thermal and electrical conductivity
Suitable for heat dissipation and low-load 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, enabling reliable fabrication.
- Lightweight material
Low density supports weight reduction in structural and decorative applications.
