Title:
WEAR-RESISTANT COPPER BASE ALLOY FOR OVERLAYING
Document Type and Number:
WIPO Patent Application WO/2005/087959
Kind Code:
A1
Abstract:
A wear-resistant copper base alloy, which has a chemical composition, in wt %, nickel: 5.0 to 20.0%, silicon: 0.5 to 5.0 %, manganese: 3.0 to 30.0 %, an element forming a Laves phase through the bonding with manganese and also forming a silicide: 3.0 and 30.0 %, and the balance: copper and inevitable impurities. Said element may be one or more of titanium, hafnium, zirconium, niobium and tantalum. The wear-resistant copper base alloy is advantageous in enhancing the resistance to cracking and machinability, is particularly suitable for use in forming an overlayed layer, and combines wear resistance, the resistance to cracking and machinability in a good balance.
