- Abstract
The production of hybrid components made of aluminium and copper offers great potential for industrial applications due to their diverse properties. This study examines the applicability of the LACE process (Lateral Angular Co-Extrusion) for the production of hybrid profiles made of copper and aluminum. The focus is on the simultaneous deformation of the aluminum and the copper reinforcing element. An existing LACE tool system was utilized to experimentally co-extrude copper alloy CuNi10 and EN AW-6082 on a 10-MN extrusion press. Subsequently, the LACE model was simulated using Finite Element (FE) simulations. Using the current tool concept and the copper alloy CuNi10, deformation is achieved neither in the cold state (20 ℃) nor in the hot state (600 ℃). However, a numerical investigation using another copper alloy with lower strength (Cu99.97) led to successful deformation of the copper reinforcement.
