6063 aluminum sheet is a heat-treatable aluminum alloy from the Al-Mg-Si (6xxx) series, commonly referred to as an architectural alloy. It is valued for its excellent surface finish, good corrosion resistance, and outstanding extrudability. Compared with 6061, 6063 offers lower strength but superior formability and surface quality, making it ideal for applications where appearance and finishing performance are critical.

Description
Features
- Medium mechanical strength
Suitable for architectural and structural applications such as window frames, doors, and curtain walls.
- Excellent corrosion resistance
Performs well in atmospheric, marine, and industrial environments; surface properties can be enhanced by anodizing.
- Excellent formability and workability
Can be easily rolled, bent, extruded, or machined, suitable for medium-to-thin gauge sheets and profiles.
- 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 under proper conditions.
- Lightweight material
Low density helps reduce overall weight while maintaining durability and structural performance.
Applications
- Architectural panels and decorative sheets.
- Doors, windows, and curtain wall systems.
- Interior and exterior decoration..
- Furniture and display structures.
- General structural and industrial components.
