Abstract
The invention relates to a method for manufacturing an aluminum tube, an aluminum tube for further processing in at least one subsequent deformation process, as well as the use of the aluminum tube. The object of providing a simple method for manufacturing an aluminum tube with elevated deformation potential is solved by texturing the outer surface of the aluminum tube using temper rolls. The application of a texture using temper rolls yields a sufficiently high roughness on the surface of the aluminum tube on the one hand, so that the strain can be increased in subsequent deformation processes. On the other hand, while the roughening of the surface can be integrated into existing manufacturing processes, e.g., for straight bead welded or extruded aluminum tubes a swift and easy manufacture of the semi-finished product is enabled.
