Aluminum Extrusion Process Extrusion Defined Extrusion is defined as the process of shaping material such as aluminum by forcing it to flow through a shaped opening in a die Extruded material emerges as an elongated piece with the same profile as the die openingHeat to melt the scrap metal charge is developed by resistance of the metal to the flow of the massive amount of electricity and by the heat of the arc itself Oxygen is injected into the EAF to speed up the melting process Fluxes and alloys may be added to EAF at the end of its melt cycle or at the ladle upon tapping the EAF to establish the
