6500 series aluminum alloy plates/sheets:
Production Process
Smelting and Casting
Smelting: Aluminum ingots and alloying elements (such as magnesium, silicon, zinc, etc.) are heated to a liquid state in a furnace according to predetermined ratios, ensuring uniformity and purity of the composition.
Casting: After smelting, the molten aluminum undergoes refining, degassing, and filtration processes before being cast into aluminum alloy ingots. These ingots will be used for subsequent processing.
Homogenization
Homogenization Annealing: The ingots undergo homogenization annealing, held at temperatures between 500°C and 600°C for a period of time to eliminate segregation produced during casting and improve the uniformity of the alloy structure.
Hot Rolling
Heating: The homogenized ingots are heated to suitable rolling temperatures, typically between 450°C and 500°C.
Initial Rolling: The heated ingots are hot-rolled through several passes to produce thick plates. After initial rolling, the plates are usually quite thick.
Intermediate and Final Rolling: The plates are further rolled in intermediate and final rolling stages to gradually reduce thickness to the desired level. Hot rolling improves the internal structure of the plates and enhances mechanical properties.
Cold Rolling
Cold Rolling Process: To achieve more precise thickness and better surface finish, the hot-rolled plates can undergo cold rolling. Cold rolling not only reduces the thickness but also enhances the strength and hardness of the plates.
Heat Treatment
Solution Treatment: After cold rolling, the plates may require solution treatment, where they are heated to approximately 540°C, followed by rapid cooling to evenly distribute alloying elements and improve material toughness.
Aging Treatment: Aging treatment is conducted at around 160°C to precipitate the strengthening phases in the alloy, achieving the desired strength level.
Surface Treatment
Surface Cleaning and Finishing: Post-production plates undergo surface treatments such as pickling, brushing, and removal of rolling oil to ensure surface smoothness and cleanliness.
Anodizing: Plates can be anodized as needed to enhance corrosion resistance and aesthetic properties.
Standards and Specifications
The 6500 series is not classified under international standards, but its production and testing adhere to the internationally recognized ISO 9001 quality management standard, with sheet production referencing the ASTM B209 standard. It has a wide range of applications, meeting the needs of various fields such as aerospace, construction, and industry.
Main Application Areas
Aerospace: Used to manufacture aircraft fuselages, structural components, and fuel tanks.
Automotive Industry: Used for car bodies, doors, engine hoods, and other components.
Construction Engineering: Used for curtain walls, roofing materials, and structural components.

Production Process
Smelting and Casting
Smelting: Aluminum ingots and alloy elements (such as magnesium, silicon, zinc, etc.) are heated in a furnace until molten to ensure uniform alloy composition.
Casting: The molten aluminum undergoes refining, degassing, and filtration before being cast into ingots, which will be used for subsequent extrusion processing.
Homogenization
Homogenization Annealing: The ingots are annealed at high temperatures for a period of time to eliminate segregation during casting and to improve the alloy's uniformity and performance.
Extrusion Molding
Heating: The homogenized ingots are heated to extrusion temperatures (typically between 400°C and 500°C).
Extrusion: The heated ingots are extruded through a die to form profiles. During the extrusion process, the aluminum is forced through the mold to create the desired cross-sectional shape.
Heat Treatment
Solution Treatment: After extrusion, the profiles are heated to around 540°C for a certain period of time and then rapidly cooled to enhance strength and toughness.
Aging Treatment: The profiles are then aged at temperatures between 160°C and 200°C to further improve strength and hardness.
Surface Treatment
Surface Cleaning: Profiles are cleaned to remove oxides and impurities, ensuring a smooth surface.
Anodizing: Profiles can undergo anodizing to improve corrosion resistance and provide a decorative finish.
Powder Coating or Electrophoresis: Based on requirements, profiles can be coated to enhance appearance and protective properties.
