Step 3: Extrusion
Extrusion process and equipment: After homogenization, the billets are ready for extrusion. Extrusion is a manufacturing process that involves forcing the heated billets through a die to create specific shapes and profiles. The billets are loaded into an extrusion press, which applies immense pressure to push the aluminum through the die.
Shaping the billet into desired forms: The extrusion process allows for the shaping of billet aluminum into various forms, such as rods, bars, tubes, and custom profiles. The die used in the extrusion press determines the final shape and dimensions of the extruded aluminum.
Step 4: Heat Treatment and Aging
Strengthening the aluminum through heat treatment: Once the billet aluminum has been extruded into the desired shape, it undergoes heat treatment to enhance its mechanical properties. Heat treatment involves heating the aluminum to a specific temperature and then rapidly cooling it to achieve the desired strength and hardness.
Aging process to enhance mechanical properties: After heat treatment, the aluminum is subjected to an aging process. Aging involves holding the aluminum at an elevated temperature for a specific duration.
