About 6063 T6 Aluminium

6063 T6 is a medium-strength architectural alloy known for its clean surface finish, high corrosion resistance and excellent workability. It is readily cut, drilled, welded and anodised, making round tube a popular choice for both structural and decorative work.

Wall Thickness

Most diameters are supplied in 10g wall (approximately 3.25mm). The 3" and 4" diameters are also available in a heavier 1/4" wall (approximately 6mm) for greater strength. Check the size table for the wall thickness of each option.

Common Uses

Handrails and balustrades, frames and structures, rollers and shafts, protective barriers, marine and transport fabrication, architectural features, and general DIY and engineering.

Finish

Supplied in a standard mill finish. The surface may show normal mill marking or handling marks typical of extruded aluminium tube. A brushed, polished or anodised finish can be applied separately if required.

Delivery Information

Lead times are currently 3-5 working days. Tube is supplied in 5m lengths, so suitable delivery access is required. If your order is long or heavy, please ensure someone is available to help with offloading on arrival.

Frequently Asked Questions

What diameters of aluminium tube are available?
12mm to 102mm outside diameter in various wall thicknesses, all in 5m lengths. Check the product page for the full range.

What is aluminium tube used for?
Handrails, furniture, curtain poles, antenna masts, flag poles, bicycle frames, marine fabrication, irrigation, display structures, greenhouse frames and lightweight structural tubework.

Can aluminium tube be bent?
Thinner-walled tube can be bent with a tube bender. Use an internal mandrel or fill with sand to prevent kinking on tighter radii. 6063 T6 bends more easily than higher-strength alloys.

What is the difference between aluminium tube and pipe?
Tube is specified by outside diameter (OD) and wall thickness. Pipe is specified by nominal bore (inside diameter). Our aluminium tube is specified by OD.

How does aluminium tube compare to steel tube?
One-third the weight, naturally corrosion-resistant, easier to cut and machine. Steel is stronger and cheaper. Choose aluminium for weight-sensitive, corrosion-exposed or architectural applications.
