6063 Aluminum Tube/Pipe

Grade: 6063

Size:

Extruded: 6mm*1mm-400mm*40mm

Seamless: 70mm*10mm-270mm*60mm

Forged: 120mm*20mm-1200mm*200mm

Standard: ASTM, AMS, BS etc.

6063 is a heat-treatable aluminum magnesium silicon alloy best known for architectural extrusions, smooth surface finish and attractive anodizing response. It offers good corrosion resistance and weldability but lower strength than common structural plate alloys such as 6061 and 6082. Although flat products may be offered by specialist suppliers, rolled plate availability and certification require specific confirmation. Extruded flat bar sold as plate must be identified correctly because its product standard and mechanical requirements differ from rolled plate.
