Abstract: In recent development of Copper-Alumina metal matrix composites, the applications which need the materials with high thermal and electrical conductivity are attracting researchers interest. Copper matrix was reinforced with Al2O3 particles with varying amounts of Al2O3 by weight were prepared by powder metallurgy (PM) route having size less than 10µm. Copper powder which is electrolytic and atomized of size 45μm are used to fabricate the MMC’s. The powder is blended and compacted at optimized load of 350, 400 & 450MPa to produce green compacts of h|/d ratio in the range 1.1 to 1.5 and sintered in hydrogen reducing atmosphere at temperature of 8000C for 1 hour. and then furnace cooled to room temperature. Wear behaviour of the composite will investigated on a pin-on-disc machine to find out effects of hardness on the composites which prepared by varying the amount of alumina in copper matrix and compare it with the previous work on the composites.
