	The paper presents the results of tube flange forming by radial extrusion. The process was carried out according to two variants: with and without the use of a limit ring. The objective of the study reported in this paper was to determine the effect of the die corner radius and the gap height on the course of the radial extrusion process, determine the limit diameter of the flange and effect of limit ring dimensions on the radial extrusion process performed with the use of this ring. The research was performed in cold working conditions with the use of tubular billet made of 6060 aluminium alloy. The analyses were based on experimental tests using a testing machine and numerical calculations based on FEM. Obtained results demonstrate that the use of a limit ring has a positive effect on the state of stress in the extruded flange, which – in turn – allows to produce flanges with relatively big diameters. Such flanges are also characterised by lower thickening than those produced by radial extrusion process without ring.
