This paper deals with the grain size and friction factor during micro extrusion process. In micro level grain size will affect the friction factor. Before the extrusion, aluminum alloys are heat treated in different temperatures and different time periods. Microscopic examination used to find the grain size of the different heat-treated components and micro extrusion was carried out to find the friction factor between die and billet and the same was related with respect to change in grain size.
