Abstract
Herein disclosed is a dispersion strengthened copper-base alloy having an excellent wear resistance, which alloy contains 5 to 30% (in weight) of nickel, 1 to 5% of silicon, 0.5 to 3% of boron and 4 to 30% of iron, the remainder being copper and unavoidable impurities, and having a structure in which hard particles composed chiefly of a silicide of iron-nickel system are dispersed in a copper-base matrix. The copper-base alloy is suitably cladded (or deposited) locally on a metallic base. The alloy may contain at least one of 0.1 to 5% of aluminum, 0.1 to 5% of Ti and 1 to 10% of Mn, if necessary, in addition to the above specified components. If necessary, 0.02 to 2% of carbon and 0.5 to 10% of chromium and/or 0.3 to 5% of titanium may be further added. Then, the structure is modified such that both the particles composed chiefly of the iron-nickel silicide and carbide particles are coexistently dispersed in the copper-base matrix.
