Then billets are moved to a tunnel heater and must be heated to approximately 800-925° F. The exact temperature is based on what the make-up of the aluminum is. Step 2. Extrusion After a billet reaches the desired temperature, it is transferred to the loader where a thin film of smut or lubricant is added to the billet and to the ram, to prevent sticking together. Then the billet is transferred to the cradle. A set of die
