PURPOSE:To manufacture easily a titled composite material through a simple stage by adhesing a steel tape to a surface to be exposed of a steel core inserted from a nipple and peeling the steel tape after Al is extruded and the steel core is coated with the Al. CONSTITUTION:A steel tape 6 is adhered to a surface 3a to be exposed of a steel core 3 inserted from a nipple installed to one wall of an extruder, and the steel core 3 is extruded in such a way that the tape 6 is in contact with a die 2 installed to the other wall of the extruder. At the time of extrusion, Al 4 is also extruded and the steel core 3 is coated with the Al 4. Then the tape 6 adhered to the surface 3a is removed and the Al film 4a coating the surface 3a is taken out together with the tape 6. |
