Abstract:
Provided is a composite material suitable for forming a part for continuous casting capable of producing cast materials of excellent surface quality for a long period of time and with which a molten metal is inhibited from flowing into a gap between a nozzle and a moving mold.A composite material (nozzle 1) includes a porous body 2 having a large number of pores and a filler incorporated in at least part of a portion that comes into contact with the molten metal, the portion being part of a surface portion of the porous body. The filler incorporated in the porous body 2 is at least one selected from a nitride, a carbide, and carbon.
