Friction stir processing (FSP) is a novel technique used for the enhancing the mechanical and metallurgical properties of the material and also to make composites of the material. In this study, an attempt is made to synthesize the composites of AA6063 and tungsten carbide particles with 5 µm particle size were added reinforcement. The tool shoulder is varied from 16 mm to 20 mm. The other parameters such as tool rotational speed of 1400 rpm and transverse speed of 50 mm/min are kept constant. The friction stir processing tool is made of high chromium high carbon steel with a pin length of 4 mm and pin diameter of 6 mm is used. The 18 mm shoulder diameter produces much finer grain size with tungsten carbide reinforced particles rather than the tools having shoulder 16 mm and 20 mm diameter. The maximum tensile strength and micro hardness achieved is 260 N/mm2 and 135 Hv respectively. In case of the tool having 16 mm diameter produces less amount of heat due to lesser contact with the workpiece material and the tool having 20 mm diameter, over heat the workpiece material due to more contact area with the workpiece and causes no proper plastization and flow of the material within the processed zone by friction stir processing and produces courser grain size.
