ABSTRACT:
A method of producing a copper-graphite particles composite alloy having good mechanical properties and good wear resistant property, which comprises preparing a metal of copper base alloy containing 0.1 to 10% by weight of Ti, Cr, Zr and/or Mg, dispersing graphite particles in the melt under agitation to form a homogeneous dispersion of the graphite particles, charging the melt in which the graphite particles are dispersed homogeneously into a heat conductive metal mold, and then applying a pressure of 150 kg/cm.sup.2 or above to the surface of the melt until the solidification of the melt is finished.
