One effective method for bending aluminum profile without cracking it is by heating the material. Heating aluminum can make it more malleable and easier to bend while reducing the risk of cracking. However, it is important to exercise caution when… Read More »How to Bend Aluminum: Heat the Aluminum – Tips (1)
When pipes and profiles are bent, it is inevitable that there will be distortion in the cross-sectional shape. The outer side of the neutral layer experiences thinning due to tangential tensile stress, while the inner side of the neutral layer… Read More »Distortion During Bending of Pipes and Profiles and Their Prevention

Two factors, wall factor, and bend radius are used to determine the severity of a bend. little or no support is needed inside the tube when the tube diameter is small and the wall is thick.
As the tube diameter increases, the tube becomes weaker. If the wall thickness of the tube decreases this too makes it weaker. The forces acting on the tube also become greater as the bend centerline radius becomes smaller.
