Forward Extrusion of Bi-metallic Components

Bi-metallic extrusion is relatively novel metal forming operation which makes possible to fabricate metallic workpieces composed of two or even more materials. In this way product with different properties at its different sections can be produced. Industrial application of this process is still relatively limited which can be partially attributed by the scarcity of technological information and knowledge related to bi-metallic deformation. Current paper outlines main characteristics and models of this technology. Experimental investigation of forward extrusion of Al (sleeve) and Cu (core) materials is elaborated.
