The paper approach some aspects of the most important parameters that influence the process of extrusion and the quality of material exiting from the die such as extrusion ratio, working temperature and speed of deformation. An important advantage gained by using extrusion of high strength aluminium alloys is that different microstructures may be obtained by varying process parameters, such that optimization of processing conditions leads to improved thermo-mechanical properties. Among the multiple process parameters in aluminium extrusion, the extrudate temperature is the most important because it determines the quality of the product and indicates the possibility of increasing extrusion speed.
