1060 Aluminum Tube

1060 is 99.6% pure industrial aluminum tube. Its core advantages are excellent electrical and thermal conductivity, good plasticity, and resistance to atmospheric corrosion. Main applications include air conditioning/refrigeration coils, heat exchanger condensers, power busbars, conductive connectors, and cooling system piping. It is also used for decorative bends, lighting accessories, and light-duty corrosion-resistant fluid transport.

How strong is 1060 aluminum tube? Can it be used for structural components?

1060 aluminum tube belongs to the 1-series industrial pure aluminum tubing category. It does not contain strengthening alloying elements and its strength cannot be increased through heat treatment. Its mechanical properties are among the lower levels of aluminum. The standard O-temper (annealed soft state) aluminum has a tensile strength of 110-136 MPa, a yield strength of approximately 40-70 MPa, and a Brinell hardness of approximately 25-35 HB. Even the H-temper tubes, after cold working, only have a tensile strength of 120-165 MPa, falling entirely into the category of soft aluminum.

Due to its relatively low strength and rigidity, 1060 aluminum tubing is unsuitable for use as load-bearing structural components. If used as load-bearing frames, supports, or heavy-duty connectors, it is highly susceptible to deformation and bending failure under stress, compromising structural stability. Its core value lies in its electrical and thermal conductivity and ease of forming, limiting its application to non-load-bearing enclosures, decorations, and fluid diversion applications, such as equipment enclosure frames, decorative moldings, and low-pressure fluid diversion pipes. For applications requiring structural load-bearing capacity, it is recommended to use 6061, 6063, or other 6-series aluminum-magnesium-silicon tubing. After T6 heat treatment, their tensile strength can reach over 260MPa, significantly improving rigidity and deformation resistance, making them suitable for various medium- and light-load structural applications.

Can 1060 aluminum tubing be bent? Will it crack?

1060 aluminum tubing possesses excellent plasticity and forming capabilities. Bending is a common processing technique, and cracking is unlikely under proper handling. O-state soft tubing, in particular, has an elongation rate of 25%-35%, exhibiting the best plasticity and supporting small-radius bending, continuous coiling, and complex multi-dimensional bending. It is the preferred substrate for refrigeration and heat exchange coils and decorative bending.

The bending effect is directly related to the tubing condition and bending radius: Under standard operating conditions, the minimum bending radius for O-state round tubing is recommended to be no less than 1.5 times the tubing diameter. Thin-walled tubing can have a smaller radius, while thick-walled tubing needs a larger radius to avoid tensile cracking of the outer wall. Hardened tubing such as H14 and H24 loses its plasticity after cold work hardening, making it prone to outer cracks when bent at large angles. It is recommended to anneal at 300-350℃ before bending to restore plasticity. In addition, using a bending mandrel and controlling the bending speed uniformly during bending can effectively avoid tube wall wrinkling and cracking, ensuring forming accuracy and tube wall integrity.
