What Is 8011 Aluminum Foil?

8011 aluminum foil is an aluminum alloy foil mainly containing aluminum, iron and silicon. Compared with pure aluminum foil such as 1235, 8011 alloy aluminum foil has better strength, better deep drawing performance and excellent processing stability.

It is one of the most commonly used aluminum foil materials for food grade packaging, household foil, container foil, pharmaceutical foil and cap stock.

8011 Aluminum Foil Specifications

• Specialized 8011 foil can be as thin as approximately 0.00018 inches (about 0.0046 millimeters), suitable for ultra-thin applications;
• And as thick as approximately 0.064 inches (about 1.63 millimeters), suitable for heavy-duty foil (non-foil grades can be even thicker).
• Widths range from a few centimeters to over 1.5 meters. Foil is typically sold in coils or master rolls; standard coil inner diameters are 75 millimeters or 150 millimeters.
• Temper (hardness) is selected according to the application: fully annealed (O) or lightly tempered states (H14, H18) are suitable for applications requiring maximum formability (such as pharmaceutical blister foil); harder tempers (H22–H26) are suitable for heavy-duty packaging or consumer foil, offering higher strength.
• Rolled (bright or matte) surface finishes are standard; we also offer special surface treatments (coated, pre-painted, or embossed).

Classification of 8011 Aluminum Foil

Features of 8011 Aluminum Foil

• Corrosion Resistance and Barrier Properties: Like other aluminum materials, 8011 aluminum foil offers excellent corrosion resistance. In foil form, it forms a tight barrier against moisture, oxygen, light, and grease, extending the shelf life of packaged products. Its surface is non-porous and inert (odorless), making it safe for food and pharmaceutical use.
• Thermal/Electrical Performance: 8011 aluminum foil exhibits excellent thermal and electrical conductivity. It can withstand moderate heating without softening, making it suitable for baking packaging and heat-sealing containers.
• Formability: The fine-grain microstructure of 8011 aluminum foil provides outstanding ductility. It can be processed through high-speed embossing, stamping, creasing, or curling without cracking or work hardening. The combination of high strength and ductility allows 8011 foil to be made very thin (saving material) while still maintaining puncture resistance during use.

These characteristics—lightweight, corrosion-resistant, high barrier efficiency, and easy formability—make 8011 the preferred choice for commercial aluminum foil.

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

Differences Between 8011 and 8021 Aluminum Foil

• 8011 Aluminum Foil: Higher strength, wide applicability, but lower elongation and puncture resistance compared to 8021.
• 8021 Aluminum Foil: More balanced performance, especially in terms of elongation and puncture resistance, suitable for high-end applications.

What is the Difference Between 8011 Aluminum Foil and 1235 Aluminum Foil?

• 1235 Aluminum Foil: Primarily used for flexible packaging, suitable for applications requiring thinness and flexibility.
• 8011 Aluminum Foil: Widely applicable, with higher strength and corrosion resistance, suitable for various packaging and industrial uses.

How to Choose Between 1235 Aluminum Foil and 8011 Aluminum Foil?

Comparative Analysis of 8011 Aluminum Foil and Other Alloy Foils

Comparison with Series 1 Pure Aluminum Foil

Series 1 pure aluminum foil (such as 1235, 1060, etc.) is the most basic aluminum foil product. Compared to 8011 aluminum foil, it offers higher ductility and deep-drawing performance, but has lower strength and rigidity. In contrast, 8011 aluminum foil maintains a certain degree of flexibility while delivering better strength and rigidity, making it more suitable for applications requiring higher strength.

Comparison with Series 3 Aluminum Foil (3003)

3003 aluminum foil primarily contains manganese (Mn). In the annealed condition, its tensile strength is slightly higher than that of 8011 aluminum foil, but in the work-hardened condition, their strengths are comparable. The elongation of 3003 aluminum foil is generally superior to that of 8011 aluminum foil, especially in medium-hardness temper conditions.

Comparison with Series 5 Aluminum Foil (5052)

5052 aluminum foil exhibits higher tensile strength and hardness, particularly in work-hardened conditions. In H32 temper, the tensile strength of 5052 aluminum foil can reach 210–240 MPa, significantly higher than that of 8011 aluminum foil in the same temper. Additionally, 5052 aluminum foil also offers better fatigue resistance and impact toughness.
