Abstract: Copper–graphite metal matrix composites possess the properties of copper, i.e. excellent thermal and electrical conductivities, and properties of graphite, i.e. solid lubricating and small thermal expansion coefficient. Copper matrix containing graphite are widely used as brushes, and bearing materials in many applications due to the excellent thermal and electrical conductivities, and the favorable self-lubricating performance. Copper-graphite with low percentages of graphite is also used for slip rings, switches, relays, connectors, plugs and low voltage d.c. machines with very high current densities. The addition of solid lubricant particles into a metal matrix improves not only the anti-friction properties, but also wear and friction properties. In the present investigation, attempts have been made for the fabrication of Cu-graphite MMC by conventional powder metallurgy route and effect of milling on the fabrication of MMCs. Copper-graphite MMCs were fabricated by mixing 1, 3, 5...
