Seamless aluminum tube is a kind of high strength aluminum alloy produced by extrusion after perforation of aluminum rod.

At Total Aluminum, we employ a variety of value-added steps to produce the highest quality seamless aluminum tubes to meet customer requirements. Seamless aluminum tubes can be made of a variety of aluminum alloys in various sizes and shapes.

There are many advantages of seamless aluminum tube, for example, no weld, the pressure vessel preferred anodic oxidation appearance more uniform, especially in the thicker wall segment can not crack weld, easy operation to improve structural integrity good mechanical properties good corrosion resistance and oxidation resistance, etc

Industrial Applications of aluminum tubes: Transportation Military and defense Marine industry Electrical busbar conductors Solar and renewable energy compressed gas storage Building and construction (commercial and residential)

Extruded tubes are hot extruded to their final size and can be seamless or non-seamless (structural tubes). In contrast to slit tubes (structural tubes), seamless aluminum tubes are tubes without any weld seams.

Our professional process for seamless tube manufacturing starts with extruding hollow tubes or drilling solid rods to our strict specifications. All aluminum seamless tubes are produced by two methods. One method is to push hollow aluminum billets through moulds and mandrel presses with great force at high temperatures. Another method is to push the solid blank through the punch, and then the mandrel perforates and squeezes the blank in a second forward stroke. No matter which method is used, the tube will not have welds or seams, making it ideal for anodizing and other finishing procedures.

In addition, All Aluminum also offers drawn aluminum tubes that are seamlessly extruded through a mold to final size. Higher precision tolerances and thinner wall thickness are available than extruded tubes.
