PURPOSE:To produce a forming material having metallic layer for non-combustible strength improvement, without aged deterioration on the surface, by dipping the face of foaming metal forming into the molten metal and then cooling and solidifying the molten metal. CONSTITUTION:For example, a metallic mold 2 corresponding to the flat shape of the foaming surface 1a, laying the metallic layer of the foaming Al plate 1 is prepared. Next, after preheating the metallic mold 2, the molten Al 3 with the prescribed temp. is poured by the quantity corresponding to the desired thickness of the forming Al layer into the metallic mold 2. Further, Al plate 1 is inserted into the metallic mold 2 and pressed. The foaming surface 1a of the Al plate 1 brought into contact with the molten metal 3 is melted and also molten metal 3 is invaded into the blow hole 1c existing on the surface 1a. Next, the molten metal 3 is cooled naturally under its condition to solidify and Al plate 1 is taken out. In this way, the molten metal is firmly sticked to the Al plate 1, and as change by heat is not generated at the joint part, the Al plate 1 improving the strength remarkably by the non-combustible Al layer is obtd.
