8006 Aluminum Foil

8006 aluminum foil is optimized for applications requiring excellent formability and barrier performance. Its unique iron-manganese composition makes it versatile, ranging from aerospace meal trays to heat exchangers. Its strength is higher than 8011 and its ductility is superior to 3003. Haomei Aluminum's 8006 aluminum foil complies with global standards (ASTM B373/B479), ensuring consistent quality.

As a high-performance 8-series aluminum alloy material, 8006 aluminum foil features high strength, good elongation, and excellent surface quality, performing particularly well in aerospace meal trays and high-end food packaging. Compared with other 8-series aluminum foils, 8006 shows significant advantages in strength, elongation, and formability, making it an ideal choice for high-end applications.

8006 aluminum foil cannot be strengthened by heat treatment. Compared with 8011 and 3003 aluminum foils, 8006 aluminum foil has higher elongation and cup height, with tensile strength superior to 8011. The core advantage of 8006 aluminum foil lies in its excellent deep-drawing formability and rigidity after forming, making it very suitable for manufacturing rigid containers that require certain support and deformation resistance.

• When selecting aluminum foil for containers, 8006 is a very good choice.
• For flexible packaging bags or pill blisters, 8011 or 1235 may be more suitable.
• The specific choice should be determined based on actual application requirements for strength, formability, and cost.

8006 aluminum foil is produced using hot-rolling technology, achieving A-grade brushed finish to ensure smooth, clean, and oil-free surfaces. The reason 8006 aluminum foil is used in aerospace anti-wrinkle food containers is that after stamping, the edges are wrinkle-free, the appearance is smooth and flat, and it exhibits excellent barrier and durability performance, performing well in packaging applications.

8006 Aluminum Foil Temper and Specifications

8006 Aluminum Foil Tempers

8006 aluminum foil is typically supplied in H18 (hard) or H19 (extra hard) temper to provide maximum strength and hardness. Sometimes, it is also available in O temper (soft) for deep-drawing processing, which hardens after forming.

• H18
• O
• H22
• H24

O temper (annealed): Fully annealed state, with the highest plasticity.

H14 temper: Work-hardened without annealing, medium hardness.

H16 temper: A higher degree of work hardening.

H18 temper: Full hard state, with the highest strength and hardness.

H19 temper: Extra hard state, with strength higher than H18.

H22 temper: Work-hardened and then partially annealed.

H24 temper: Work-hardened followed by partial annealing.

H26 temper: Work-hardened followed by near-full annealing.

H28 temper: Work-hardened followed by light annealing.

Among these, O temper is mainly used in scenarios requiring deep drawing or complex forming; H18 is suitable for applications requiring high strength and hardness; H22, H24, etc., balance strength and formability and are suitable for most meal box forming applications.
