7050 T7651 Aluminum Plate Sheet Processing

1. Solution Heat Treatment

• Purpose: To dissolve the alloying elements completely into the aluminum matrix, enhancing the strength and hardness of the alloy.
• Process: Heat the aluminum alloy to a specific temperature, maintain it for a set time, and then rapidly cool it (typically by quenching).

2. To eliminate internal stresses generated during processing

• Purpose: To eliminate internal stresses generated during processing, reducing the risk of deformation and cracking.
• Process: Stretch the 7050 aluminum alloy to remove internal stresses with a specific amount of stress. The amount of stretching is determined based on the type of aluminum product being manufactured (thin sheets, plates, bars, or forgings).

3. Age the aluminum alloy at a controlled temperature

• Purpose: To further improve the strength and stability of the 7050 alloy and optimize exfoliation corrosion resistance.
• Process: Age the aluminum alloy at a controlled temperature, with the duration set according to specific requirements. The degree of aging treatment is chosen to maximize exfoliation corrosion resistance and ensure stable performance of the alloy.
