The manufacturing equipment is simple and the equipment price is low. Since the coating is solidified by controlling the shape of the drawn portion in the bath or immediately after leaving the bath, there is no uneven thickness of the coating. Further, solidification of the molten metal or alloy mainly occurs only at the interface with the coating layer, and no nucleation occurs at other portions, so that a coarse crystal or a single crystal that is long in the drawing direction is formed. Therefore, the metal composite material according to the method of the present invention has a great advantage that it has few pinholes in the coating layer and has extremely excellent workability.
