Wear-resistant copper-base alloy.

摘要

A wear-resistant copper-base alloy having superior self-lubricity includes, by weight %, Ni: 10.0 to 30.0%; Si: 0.5 to 3%; Co: 2.0 to 15.0%; at least one metal selected from the group consisting of Mo, W, Nb and V: 2.0 to 15.0%; and the balance being Cu and unavoidable impurities, and having a structure in which hard phase grains containing 5 vol% or more of silicide of at least one metal selected from the group consisting of Mo, W, Nb and V are uniformly dispersed in an amount of 10 to 60 vol% in a copper-rich matrix, to which 2.0 to 15.0% of Fe and/or 1.0 to 10.0% of Cr may be further added.
