The Best Aluminum Alloy Raw Material For Household Foil

Household foil generally refers to aluminum foil, which is a metal foil with aluminum as the main component, with good ductility, пластичност, corrosion resistance and conductivity. The main purpose of household foil is to package food, отпоран на влагу, антиоксидација, fresh-keeping, итд., and it is widely used in daily life. Household foil needs to have good fresh-keeping performance, sealing performance and corrosion resistance. Household foil is mainly made of aluminum, and there are 1-8 series of aluminum alloys. What aluminum alloy is the best choice for household foil?

This article will tell you which aluminum alloy is the most suitable for household foil?

Aluminum alloy suitable for household foil

Among the 1000-8000 series aluminum alloys, the alloys commonly used as household foil materials are 3003, 8011, 8079 и друге легуре.
3003 легура is a Mn alloy containing 1.0%~1.5% Mn, 0.6% И, and a small amount of Fe, Cu and other elements. It has good corrosion resistance, formability and welding performance, and is widely used in the production of air conditioner radiators, fuel tanks, итд.

8011 легура is an Al-Fe-Si alloy containing 0.5%~0.9% Fe, 0.25% Si and a small amount of Cu, Mg and other elements. It has good toughness and ductility, and is suitable for making food packaging materials, containers, lids, итд.

8079 легура is an Al-Zn-Mg alloy containing 0.12%~0.15% Zn, 0.05% Mg and a small amount of Cu, Fe and other elements. It has high strength, high elastic modulus and good corrosion resistance, and is suitable for making various composite packaging materials.

Among these three alloys, 8011 aluminum foil is the most common raw material for household foil. Алуминијум 8011 foil has good toughness and ductility, and is easy to process and form. У исто време, it also has strong insulation properties, and neither air nor light can penetrate, so it is very suitable for food packaging materials, such as aluminum foil lunch boxes, food preservation aluminum foil, итд.

8011 household aluminium foil

Household aluminium foil made of 8011 aluminium alloy has excellent properties. 8011 aluminium foil is a versatile and widely used material. 8011 aluminium alloy belongs to the 8xxx series, which are aluminium alloys containing other elements to improve strength, durability and performance. The main components of 8011 alloy are.
Aluminium (Ал): 97.5-98.5%, Гвожђе (Фе): 0.6-0.75%, Силицијум (И): ~0.5-0.8%, and also contains small amounts of copper, манган, magnesium, zinc and titanium, обично мање од 0.1%. This alloy composition gives alloy foil 8011 добра отпорност на корозију, formability and welding properties. It has higher strength than pure aluminium and good polishing properties, and can maintain a bright surface for a long time.

Properties of 8011 alloy that make it suitable for use as household foil

Good formability and ductility

One of the key properties required for household foil is excellent formability. 8011 alloy can be easily rolled into very thin sheets without cracking or breaking, even when the foil is less than 0.01 mm thick. Its ductility and plasticity allow it to be folded or crumpled, making it ideal for packaging food.

Висока отпорност на корозију

Aluminum naturally forms a protective oxide layer that resists corrosion. This makes 8011 alloy an excellent choice for household foil as it prevents interaction with moisture, chemicals, and food. It ensures that the foil remains stable and is safe for contact with food.

Non-toxic and safe for contact with food

The composition of the Aluminum 8011 foil alloy ensures that it is non-toxic and safe for contact with food. It does not react with most foods, which is crucial when used for cooking or storage.

Lightweight but strong

Although thin and lightweight, легура алуминијума 8011 has significant strength and durability and can be used for a variety of purposes around the home. This makes it ideal for everyday tasks such as food packaging, grilling, and storing leftovers.

Barrier Properties:

One of the most important properties of household aluminum foil is its ability to act as a barrier against light, ваздух, влаге, и бактерије. 8011 alloy is highly impermeable to these elements, helping to preserve the freshness and quality of packaged foods.

Thermal Conductivity:

Aluminum is an excellent conductor of heat, which makes 8011 alloy ideal for uses that require heat management, such as baking and cooking. It can withstand high temperatures without deforming or maintaining integrity.

Recyclability

Another advantage of 8011 alloy is that it is fully recyclable. This increases its appeal to environmentally conscious consumers and industries. The recycling process for aluminum is energy efficient, making it a sustainable choice.
