The present study is concerned with the hydrostatic extrusion process of copper-clad aluminum rod through metallurgical joining. In this study, the rigid plastic finite element program, HICKORY, is used to analyze the steady state extrusion process of the bimetal rod. Simulations are performed for copper-clad aluminum rod with several extrusion ratio to give the distributions of effective strain rate, equivalent stress and hardness. Experiments are also carried out for aluminum-inserted copper rod at room temperature. It is found out that finite element predictions are generally in good agreement with the experimental observations. The detail comparison of the extrusion loads by the finite element method with those by experiments are given.
