ABSTRACT:
Hard phase particles including Co alloy particles, carbide alloy particles, and silicide particles are dispersed substantially uniformly throughout a matrix composed of Cu self-fluxing alloy of a cladded portion. The cladded portion contains 6 to 15% by weight of Co, 3 to 8% by weight of one of Cr and Mo, 0.3 to 1% by weight of W, 0.5 to 1.8% by weight of Fe, 8 to 15% by weight of Ni, 0.08 to 0.2% by weight of C, 1.5 to 4% by weight of Si, 0.5 to 0.8% by weight of Al, and 0.1 to 0.3% by weight of P, and inevitable impurities and Cu as a balance. The hard phase particles have an average particle diameter of 8 to 20 μm and a particle size distribution width of 0.1 to 100 μm, and to occupy 10 to 20% in an arbitrary cross section of the cladded portion.
