ABSTRACT:
This is to provide a build-up wear-resistant copper-based alloy, which is advantageous for enhancing the cracking resistance and machinability, which is appropriate for cases of building up to form built-up layers especially, and which is equipped with the wear resistance, cracking resistance and machinability combinedly in a well balanced manner. A build-up wear-resistant copper-based alloy is characterized in that it has a composition, which includes nickel: 5.0-20.0%; silicon: 0.5-5.0%; manganese: 3.0-30.0%; and an element, which combines with manganese to form a Laves phase and additionally to form silicide: 3.0-30.0%; by weight %, and inevitable impurities; and additionally the balance being copper. The element can be one member or two or more members of titanium, hafnium, zirconium, vanadium, niobium and tantalum.
