More Information
Summary:A process is disclosed for the manufacture of aluminium-graphite particulate composite using uncoated graphite particles for automobile and engineering applications. In the process the aluminium-alloy melt is treated with a reactive metal to increase the wettability of the alloy and the graphite particles. Further treatment of the melt and gradual addition of activated graphite powder and stirring at about 500 to about 600 r.p.m. at a temperature of about 700 DEG to about 720 DEG C. result in the composite.
