PURPOSE: To develop a Cu alloy having excellent strength, toughness and wear resistance by adding specific elements to Cu and dispersing and incorporating fine grained intermetallic compounds into the structure of the Cu alloy.

CONSTITUTION: 17W40%, by weight, Zn, 2W11% Al, 0.005W0.5% Si, one or more kinds among 0.1W3.5% Ti, Zn and V, one or more kinds among 0.003W0.3% P, Mg and Ca, one or more kinds among 0.02W3.0% Fe, Ni and Co are added to Cu, or 0.1W4% Mn, 0.05W2.5% Sn and 0.05W1.5% Pb are furthermore independently or Mn and Sn, Mn and Pb, Sn and Pb, Mn, Sn and Pb are compositely added thereto. The Cu alloy having the structure in which the fine grains of the intermetallic compounds having 3W50μm average grain size are dispersed and incorporated into the alloy matrix at 1W20% areal ratio, having excellent strength, toughness and wear resistance and having high friction coefficient can be obtd.
