What is household foil?

Household foil, also called household aluminum foil and commonly referred to as aluminum foil, is a thin sheet of aluminum used for a variety of household purposes. It has become a must-have for many households due to its versatility, durability, and convenience.

Household aluminum foil is usually made of aluminum alloy, which combines the characteristics of pure aluminum with the advantages of additional elements to improve functionality. The most commonly used alloy for household aluminum foil is 8011 aluminum alloy.

Main properties of 8011 aluminum foil alloy:

1. Good formability: 8011 aluminum alloy has excellent formability, which can be rolled into very thin sheets, which is essential for aluminum foil applications.
2. Corrosion resistance: This alloy has strong corrosion resistance, which is important for food storage and packaging.
3. High ductility: 8011 alloy has high ductility, making it easy to form and wrap around various objects.
4. Heat resistance: It can withstand high temperatures and is suitable for cooking applications such as baking and grilling.
5. Non-toxic and safe: It is non-toxic and safe for food use.


8011 aluminum alloy usually includes:
– **Aluminum (Al)**: 97.5% – 99%
– **Iron (Fe)**: 0.6% – 1%
– **Silicon (Si)**: 0.5% – 0.9%
– **Other elements**: small amounts of elements such as manganese (Mn), copper (Cu), zinc (Zn) and magnesium (Mg).

These characteristics and composition make 8011 aluminum alloy the most suitable choice for household aluminum foil.
