Abstract
Provided is a copper-base alloy with excellent wear resistance. The wear-resistant copper-base alloy includes, by mass %: 5.0 to 30.0% nickel; 0.5 to 5.0% silicon; 3.0 to 20.0% iron; less than 1.0% chromium; less than or equal to 5.0% niobium; less than or equal to 2.5% carbon; 3.0 to 20.0% of at least one element selected from the group consisting of molybdenum, tungsten, and vanadium; 0.5 to 5.0% manganese and/or 0.5 to 5.0% tin; balance copper; and inevitable impurities, and has a matrix and hard particles dispersed in the matrix, when niobium is contained, the hard particles contain niobium carbide and at least one compound selected from the group consisting of Nb—C—Mo, Nb—C—W, and Nb—C—V around the niobium carbide, and when niobium is not contained, the hard particles contain at least one compound selected from the group consisting of molybdenum carbide, tungsten carbide, and vanadium carbide.
