This paper focuses on the extrusion process of powder/solid clad rods with the desired hole ratio in the center to reduce the weight. The finite-element model about a lot of deformation body extrusion was successfully demonstrated. Raw steel powder and steel tube were consisted as powder/solid rods. While the obvious plastic deformation proceeding in deformation region, the hole ratio clearly lessened, then a little rose apart from the deformation region. The deformation parameters were determined for the purpose to lesson the weight of the rod to about 15% hole ratio in powder deformation region. The extrusion experiment and the tensile property test proved that the integrative property improved while the weight was reduced. The clad rod can be utilized in the solid suck rods.
