8011 and 3003 are common aluminum alloys used to make foil, but differ in alloy composition and properties. 8011 contains iron and silicon, making it durable and corrosion-resistant, while 3003 contains manganese, which improves its flexibility, elongation, and formability. This makes 8011 ideal for applications where package integrity is key, like pharmaceuticals, while 3003 is often used for complex-shaped food containers due to its enhanced strength and ductility.

8011 aluminum foil

Composition: Primary alloying elements are silicon and iron.

Properties: Higher strength, better corrosion resistance, and excellent integrity for sensitive items.

Best for: Packaging for delicate products like medications and perishable foods where barrier properties are crucial.

3003 aluminum foil

Composition: Contains manganese as the primary alloying element.

Properties: Superior strength and elongation, making it very formable and ductile.

Best for: Complex-shaped food containers, airline trays, and other items that require deep drawing or stamping without rupture.

What metal is 3003 Alloy Aluminum Foil?

3003 alloy aluminum foil is a medium-strength alloy with excellent atmospheric corrosion resistance, very good weldability, and good cold formability. Compared to 1000 series alloys, it has higher elongation and tensile strength, especially at elevated temperatures.

The main states of aluminum foil 3003 include H 18, H22, H24, and other states upon request.

8011 aluminum foil introduction:
8011 aluminum foil is mainly added with Fe, Si and other elements. 8011 aluminum foil has clean surface, uniform color, no flower spots and hollows, and can be custom produced according to customers' needs.
Because of its excellent moisture-proof performance, light-shielding performance and high blocking ability, it is often used as food packaging foil and pharmaceutical aluminum foil. Due to its strong mechanical properties, it can be used as bottle cap material.
