Forging is a metal production process with a long history. The advantage of forging production lies in the fact that it cannot only obtain the shape of mechanical parts but also improve the internal organization of materials and improve the mechanical properties. Due to the excellent performance of aluminum and aluminum alloys, it is widely used in machinery, electricity, electronics, automobile, ship, construction, instrumentation, hardware, and household products and other fields. Therefore, for important mechanical parts with high mechanical properties and high load capacity, they are mainly produced by forging aluminum. The weight of aluminum forgings represents 77% in aircraft, 68% in tanks and 76% in cars.
