Tungsten reinforced copper composite is one of the alternatives widely used in sliding contact and high voltage electric contact heat sink materials etc. Mechanical alloying accomplished by compaction, sintering and extrusion techniques were used to prepare the composite. It is necessary to know the tribological behavior of Cu-W composite material.Wear behavior depends on many parameters such as the weight percentage of tungsten, sintering temperature, load and sliding distance to predict multiple material characteristics such as hardness, wear volume, and coefficient of friction. This paper proposes to explain and monitor the wear behavior of Cu-W composite material using pin-on-disc test conducted under different sliding distance and at 20N load while the velocity remains constant. The SEM & XRD analysis will be used to evaluate the characteristics of Cu-10%W composite materials
