Zusammenfassung:Provided is a composite for a wear-resistant ring having excellent heat conductivity. In the composite for a wear-resistant ring, an iron-based sintered compact for a wear-resistant ring having a composition that contains, by mass, C of 0.4 to 1.5% and Cu of 20 to 40%, and having a structure in which pores exist continuously at a porosity of 15 to 50% in terms of volume fraction, and in which a matrix is pearlite, and in which a free Cu phase or further dispersion particles are dispersed in the matrix, is insert-cast in an aluminum alloy, and has the pores impregnated with the aluminum alloy.
