This paper described extrudability and bonding strength of copper (TPC) clad aluminumalloy (pure Al, Al3003, Al5005, and Al7072) composites produced by indirect extrusion at 350°Cwith extrusion ratio of 21.39. Conical typed die with semi angle of 30°. Carbon oil was used to reducethe friction between billet/sleeve and billet/die. Maximum extrusion pressure was estimated to491MPa for the Cu/Al, 714MPa for the Cu/Al3003, 820MPa for the Cu/Al5005, and 743MPa for theCu/Al7072 alloy composites. No surface fracture was observed. From SEM observation, diffusionlayer between the sheath material and the core material of extruded composites is observed and itsthickness was measured to about 1.5㎛. The bonding strength was estimated to 65MPa for the Cu/Al,89.3MPa for the Cu/Al3003, 70MPa for the Cu/Al5005, and 75MPa for the Cu/Al7072 alloycomposites
