China Aluminum Industry Network reports that different annealing and heat treatment processes are commonly used in the aluminum industry to improve material properties, such as strength, ductility, and dimensional stability. Here are some typical procedures: 1. Homogenization Annealing: This process involves heating the material to a temperature range of 480–495°C. After reaching the desired temperature, it is held for 12 to 14 hours to allow uniform distribution of alloying elements. The part is then cooled slowly in the furnace to minimize internal stresses. 2. Full Annealing: In this method, the material is heated to 390–430°C and kept at that temperature for 30 to 120 minutes. Once the holding time is complete, the material is cooled in the furnace until it reaches 300°C, after which it is air-cooled to room temperature. This helps reduce hardness and improve machinability. 3. Rapid Annealing: This technique is typically used when faster processing is required. The material is heated to 350–370°C and held for 30 to 120 minutes. Afterward, it is air-cooled, making this method suitable for applications where minimal distortion is important. 4. Quenching and Aging: This two-step process starts with quenching, where the material is heated to 495–505°C and rapidly cooled using water. Following quenching, aging is performed either artificially or naturally. Artificial aging takes place at 185–195°C for 6 to 12 hours, followed by air cooling. Natural aging occurs at room temperature over a period of 96 hours, allowing the material to reach its optimal mechanical properties over time. These heat treatment methods are widely applied in the production of aluminum alloys to achieve specific mechanical characteristics and ensure long-term performance in various industrial applications.
