Production Process of 8011 Aluminum Foil
The production process of 8011 aluminum foil is complex and involves multiple precise processing steps:
Melting and Casting
High-purity aluminum ingots and appropriate amounts of Fe, Si, and other alloying elements are placed into a furnace and heated to 720–750°C to fully dissolve and mix the elements. The molten alloy is then cast into ingots.
Heating and Hot Rolling
The ingots are heated in a furnace to 400–450°C and then hot rolled in multiple passes to reduce the thickness from several hundred millimeters to 6–10mm.
Cold Rolling
The hot-rolled plates are cold rolled in multiple passes to reduce the thickness to the target range (0.1–0.5mm). Intermediate annealing is performed during cold rolling to eliminate work hardening.
Foil Rolling
The aluminum sheet after cold rolling and annealing is further processed into foil. For ultra-thin foil under 0.012mm, double-roll tandem rolling (stack rolling) is used to mass-produce 0.006mm–0.03mm single-side bright foil.
Slitting and Surface Treatment
According to customer needs, the foil is slit to the required width and length. Surface treatments such as oiling, painting, and coating can also be applied.
Price Influencing Factors of 8011 Aluminum Foil
- Raw material price: Fluctuations in aluminum ingot prices directly impact cost and selling price
- Alloy composition and processing: Proportion and purity of alloying elements affect performance and production cost
- Specification and temper requirements: Higher demands in thickness, width, and temper result in higher prices
- Surface treatment: Additional steps like oiling, painting, and coating increase cost
- Minimum order quantity and lead time: Larger orders result in lower unit prices; shorter lead times may incur rush fees
