The commercial extrusion machine has been used for the extrusion of copper circular rod of diameter 12.5 mm. Microstructure analyses of the extruded products of Copper before and after deformation (extrusion) have been carried out. Material properties of Copper have been found using tensile and hardness test. It is observed that more uniform and homogeneous grains are obtained after extrusion. It is observed that the tensile strength of the extruded product increases by 6.8 % after extrusion of material and the braking load is increased by 22.9%.

INTRODUCTION Extrusion is an important metal forming process having applicability in industrial as well as domestic sectors. Extrusion is the process by which a block of metal is reduced in cross section by forcing it through a die orifice under high pressure [11,
