Abstract
A hardfacing alloy satisfies the following condition when the hardfacing alloy as a whole is 100 mass % (also simply referred to as '%,' hereinafter), Ni: 10-25%, Si: 1-3%, Fe: 3-18%, the total of one or more elements of Mo, W, and Nb: 6.5-20%, and the balance: Cu and impurities. In particular, it preferably satisfies Fe+2Mo≥22.6(%), Mo equivalent/Fe≥1.17, and Mo equivalent=Mo+0.522W+1.033Nb. In a hardfacing part composed of the hardfacing alloy, coarse hard particles are formed to ensure the wear resistance, and a soft phase present in the hard particles ensures the machinability. This may be understood as a raw material powder for hardfacing treatment and may also be understood as a hardfacing member in which a hardfacing part is formed on a base material using the raw material powder.
