Particulate reinforced Composites made of aluminum and Silicon Carbide may be considered as suitable replacement for steel in industrial and automotive applications. The high strength and good wear properties makes the composites useful. Magnesium is used to increase the wet properties of Silicon Carbide to mix with aluminum. The furnace temperature effect during the composite manufacturing was studied experimentally to test for wear properties .The manufactured composites in liquid route were tested in DUCOM wear testing machine at sliding speed of 2.5 m/s with load 30N and at different sliding distance in atmospheric conditions . The furnace temperatures are maintained at 7000C, 8000C and 9000C for composite preparations. The samples are tested for wear behavior and specific wear rate was compared for different composites.
