Zusammenfassung:	PURPOSE: To produce a resin finishing machine member for compound, excellent in corrosion resistance and wear resistance, by specifying the composition of a composite material in which hard layers composed essentially of carbides and borides are dispersed in an Ni-base matrix. CONSTITUTION: This composite material has a composition consisting of, by weight ratio, 2-6% B, 21-38% Cr, 8-22% Mo, 0.5-12% W, 3-6% Fe, 0.4-3% C, 0-2% Cu, 2-20% Ti or/and 1-5% Ta, and the balance Ni with inevitable impurities. It is preferable to further incorporate
