PCT No. PCT/JP79/00211 Sec. 371 Date Apr. 11, 1980 Sec. 102(e) Date Apr. 11, 1980 PCT Filed Aug. 9, 1979 PCT Pub. No. WO80/00352 PCT Pub. Date Mar. 6, 1980.A process for preparation of graphite-containing aluminum alloys includes incorporating graphite particles into an aluminum containing melt. When the graphite particles are incorporated, floating of the graphite particles to the surface of the melt is prevented by the use of certain additive metals. Before the graphite particles are incorporated into the melt, titanium, chromium, zirconium, nickel, vanadium, cobalt, manganese, niobium or phosphorus is incorporated and dispersed into the melt. The produced aluminum alloys are suitable to use as dry frictional contacts such as bearings.
