Aluminium tube bending is one of our most important tube bending services.
Unlike steel, aluminum is a more “tender” metal and so it might seem logical to think that bending it is simpler, but it doesn’t work that way. Commercially the most common aluminium temper is T5 (cooled after processing). This temper has technical characteristics that do not make it suitable for the bending of aluminium tubes and pipes.
Depending on the temper you are using – other important tempers include T6, T4 and T1 – aluminium tubes will respond differently to bending. This percent elongation for aluminium needs to be evaluated correctly to avoid jeopardising the outcome of the process. It is therefore essential, during the feasibility study (or design stage), to determine the precise characteristics needed for the material to avoid the following during bending:
- Breakage of the aluminium tube
- “Substantial” differences and/or deformations in the aluminium tube after tube processing
Drawing on its long experience, Tecnocurve works alongside its clientele as a reliable partner in the field of cold shaping of tubular elements in aluminium. Recommendations are made about the technical and physical specifications of the temper to obtain high-precision aluminium bending results.
Bending aluminium tubes, tubular sections and bars
The bending process for aluminium involves the following elements:
- Tubular sections
- Extruded section bars
