Abstract

The use of clad material as a structural material is increasing in many industries because it has material properties that cannot be obtained from a single material. For the present study, a hot forward extrusion process was applied to fabricate aluminum/copper (Al/Cu) clad composite rod. The different of extrusion ratios and die angles were applied to obtain the best extrusion condition. Finally, hot forward extrusion process was applied at a temperature of 480 ◦ C with extrusion ratio of 4 and Die angle of 45. The purpose of this paper was fabrication of Al-clad Cu rods by hot forward extrusion. Materials that used in this research were aluminum alloy of AA7075 and pure commercial copper as clad material. There were some experiments among pure copper, AA7075 (both without any extrusion and cold work) and Al-clad Cu rods that included Mechanical Tensile Tests, Micro Hardness tests and Microstructure compare. Microstructure characterizations of the Al/Cu interface and the neighboring regions revealed the formation of a suitable and adhesive bonded layer with thickness of 22 microns and acceptable Microhardness. The mechanical properties results of AA7075, copper and two layer Al/Cu rods reveal that the Yield strength, Ultimate Tensile strength and Formability of extruded Al/Cu rods are suitable in compare to single material rods consist of AA7075 and copper rods.
