PURPOSE:To obtain a porous metal in which blank materials are securely bonded to each other by cutting the blank material formed by cladding a low- melting Al alloy to the surface layer of an Al core material to a chip shape, etc. and heating the same in a molding tool. CONSTITUTION:The low-melting alloy 2 of Al-Pb, Al-Sn or Al-Pb-Sn is thinly clad on the surface layer of the core material 1 consisting of Al, Al alloy. The clad blank material is cut to a tip, fiber or wire shape. The cut blank materials are packed into the molding tool where the materials are heated to the liquidus line temp. of the low-melting alloy + or -10 deg.C and is molded under the pressure. The molding is then forcibly air cooled. The porous aluminum welded with the cut clank material metal 1 by the low-melting alloy 2 can be molded to a desired shape by the above-mentioned method. The porous aluminum has high mechanical properties and above all, ductility and permits easy bending, machining, etc.
