Abstract: PURPOSE: A producing method of an aluminum/copper stratified compound material is provided to produce an aluminum/copper stratified compound material by using an indirect extrusion. CONSTITUTION: An aluminum(12) core material and a copper(11) coating material are bonded and fixed to form a billet. An extruded billet is lubricated, heated at a temperature of 200°C and higher, inclined-heated by being inserted to a container having its temperature adjusted to be higher than that of the billet, and extruded in a die angular degrees, dihedral angle, 2theta is 90 angular degrees or less. Thereby, an aluminum/copper stratified compound material is produced. The fixation of the core material and the coating material is performed by a mechanical bonding or a pressurizing casting. The lubrication is performed by spreading a mixture of graphite powder and mineral oil having 1000 mesh and less. The inclined-heating is performed in the condition of from 200°C to 350°C of billet temperature and from250°C to 400°C of container temperature.
