Aluminum tube is a hollow metal product made from aluminum and its alloys, valued for being lightweight while still offering useful mechanical strength. It is widely used wherever a strong but low-weight tubular component is needed.

Aluminium tube and aluminium pipe are available in many cross-sections. Round tubing is the most common form, while square, rectangular and specially shaped profiles can also be supplied. Tubes may differ in outer diameter, wall thickness and length, and they can be produced as seamless or as welded tube depending on the manufacturing route.

Aluminum offers a good strength-to-weight ratio and good thermal and electrical conductivity. It forms a natural oxide layer on the surface that helps it resist corrosion under ordinary conditions, and it is easy to cut, drill, bend, thread and join, which makes aluminum tubing convenient for further fabrication. Aluminum is also fully recyclable, and recycled aluminum keeps its useful properties.

When specifying aluminum tube, the main parameters are the outside diameter, the wall thickness and the length. Wall thickness largely determines the stiffness of the tube, while the diameter defines its overall size and the length is set by the cutting plan. Suppliers usually state tolerances for diameter, wall thickness, straightness and length, and these tolerances should be checked against the requirements of the final part.

The surface of aluminum tubing can be left as mill finish or treated in different ways to change its appearance and surface behaviour. Mechanical finishes such as brushing or polishing alter the look of the surface, while coating and electrochemical treatments can provide additional protection and colour. The choice of finish is normally made according to the visual and functional requirements of the finished product.

Choosing the right aluminum tube or aluminium pipe usually involves balancing several factors: the required strength and stiffness, the working environment, the available space, the weight limit and the target cost. In many projects a lighter tube can replace a heavier one without losing the needed performance, which is one reason aluminum tubular products are popular in transport, construction and equipment manufacturing.

Aluminum tube is commonly supplied in standard stock lengths and can be cut to the required size. Buyers should confirm the alloy, temper, dimensions, tolerance class and surface condition when placing an order, and it is helpful to provide drawings or samples when a non-standard profile is needed.
