8006 Aluminum Foil Production Process
Melting and Casting
The production of 8006 aluminum foil begins with the melting and casting process:
Raw Material Preparation: Using aluminum ingots with purity ≥99.45% and appropriate alloying elements
Melting: Raw materials are loaded into the melting furnace and heated to 720–750°C until fully melted
Refining: Degassing and inclusion removal are carried out by gas stirring and adding refining agents
Filtration: Ceramic filter plates are used to ensure melt cleanliness
Casting: The melt is cast into ingots or directly cast-rolled into slabs
Rolling Processing
Rolling is the core process in 8006 aluminum foil production:
Hot Rolling: The ingot is heated to 400–450°C and hot rolled through multiple passes to reduce thickness from 600–700 mm to 3–5 mm
Cold Rolling: Carried out at room temperature to further reduce the thickness to 0.2–0.24 mm
Foil Rolling: Specialized foil rolling mills reduce the strip to final thickness, typically 0.006–0.2 mm
Heat Treatment
Heat treatment greatly influences the final properties of 8006 aluminum foil:
Homogenization Annealing: Eliminates internal stress generated during rolling and improves the material’s microstructure
Intermediate Annealing: Conducted during multi-pass rolling to enhance plasticity
Final Annealing: Determines the final temper and performance of the aluminum foil
Surface Treatment
Surface treatment processes include cleaning, oiling, passivation, etc., which are critical to the final application performance of the foil.
Finishing Operations
Finishing operations include:
Slitting: Cutting large coils into customer-specified widths
Inspection: Comprehensive inspection of dimensions, surface quality, and physical properties
Packaging: Packing according to customer requirements to ensure damage-free transportation and storage
