Description
Features
- Superior corrosion resistance
Performs exceptionally well in marine, chemical, and industrial environments, ideal for outdoor, coastal, and architectural applications.
- High mechanical strength
Stronger than standard 5052 series, suitable for medium-to-high-strength structural and decorative applications.
- Excellent formability and workability
Can be rolled, bent, stamped, and deep-drawn, suitable for medium-to-thin gauge processing and moderate forming.
- Smooth and uniform surface finish
Ideal for anodizing, painting, coating, embossing, or film lamination for both decorative and functional purposes.
- Good weldability
Compatible with TIG, MIG, and spot welding, ensuring reliable fabrication.
- Lightweight material
Low density helps reduce overall weight while maintaining strength and durability.
Applications
- Marine and shipbuilding panels.
- Chemical equipment and storage tanks.
- Transportation and vehicle bodies.
- Architectural panels and facades.
- Industrial equipment and structural components.
