Description
Features
- Good mechanical strength
Provides medium-to-high strength suitable for structural applications in construction, transportation, and machinery.
- Excellent corrosion resistance
Performs well in atmospheric, marine, and chemical environments; can be further improved by anodizing.
- Good formability and workability
Can be rolled, bent, stamped, and machined easily, suitable for medium-to-thin gauge sheets and complex shapes.
- Smooth and uniform surface finish
Ideal for anodizing, painting, coating, or film lamination for both decorative and functional purposes.
- Good weldability
Compatible with TIG, MIG, and spot welding; post-weld heat treatment recommended for maximum strength.
- Lightweight material
Low density reduces overall weight while maintaining structural performance.
Applications
- Structural components and frames.
- Truck bodies, trailers, and refrigerated truck panels.
- Marine structures and ship components.
- Machinery parts and industrial equipment.
- Aerospace and transportation components.
- Mold bases, jigs, and fixtures.
