An aluminum round tube is a non-ferrous, round, hollow aluminum product used in many structural applications. Aluminum round tubes are typically manufactured through extrusion, where a heated aluminum billet is forced through a shaped die to create a continuous tube length with a circular cross-section. They can also be drawn seamlessly. Purchase it online or at any Metal Supermarkets location, cut to your exact specifications.
Aluminum round tubes come in a wide range of different finishes, including anodized. The interior is generally smooth with no seams. It is available in two variants: a more affordable extruded structural aluminum round tube or a more expensive drawn seamless form for those higher precision applications.

Benefits of Aluminum Round TubesAluminum round tubing is generally favored for projects where strength, lightweight, and corrosion resistance are key considerations. Here are some benefits of using aluminum round tubes:Lightweight – Aluminum round tubes are low-density, making them significantly lighter than many other metals. This lightweight nature is advantageous in applications where weight reduction is essential, such as transportation, aerospace, and portable structures. It eases handling, transportation, and installation while still providing structural integrity.
Strength-to-Weight Ratio – Although lightweight, aluminum round tubes exhibit high strength and an impressive strength-to-weight ratio. This property allows for light and efficient structures without compromising strength and durability. It is particularly valuable in applications where load-bearing capacity is essential.
Corrosion Resistance – Aluminum round tubes naturally form a thin, protective oxide layer on their surface, which provides excellent corrosion resistance. The oxide layer acts as a barrier, protecting the underlying metal from environmental factors, moisture, and corrosive substances. This corrosion resistance ensures long-term durability and reduces maintenance requirements.
Thermal Conductivity – Aluminum has excellent thermal conductivity, making aluminum round tubes suitable for heat transfer applications. They efficiently dissipate heat and can be used in heat exchangers, radiators, and other thermal management systems.
Versatility and Formability – Aluminum round tubes can be easily formed, shaped, and fabricated to meet specific requirements. They can be cut, welded, bent, or joined using various techniques. This versatility enables customization and flexibility in designing structures or components for different applications. However, if you need to weld your tubes, remember that aluminum tubes need special procedures to be welded because the welding wears off from tooling.
