Aluminum foil is a soft metal film. According to the thickness, it can be divided into heavy gauge foil, medium gauge foil and light gauge foil(double zero aluminum foil). Their thickness respectively are 0.1-0.2 mm, 0.01-0.1 mm and 0.005-0.009 mm.
According to the different alloy series, the commonly used alloys of aluminum foil are 1 series, 3 series, and 8 series aluminum foils. Of them, 8011, 3003,8021 and 1060 aluminum foils are more popular.
Different Alloys
8011 Aluminum Foil
8011 aluminum foil mainly contains Mn and Mg elements, which is of high strength. It is widely used in pharmaceutical packaging, food packaging, aluminum food container, aluminum foil tape, cable foils, milk cap materials, bottle cap materials and many other fields.
3003 Aluminum Foil
The common temper of 3003 aluminum foil is H24. It is often used as aluminum foil container for food packaging after punching. 3003 aluminum foil is of outstanding barrier properties, light weight, good tightness and good insulation. Besides, 3003 aluminium foil is also widely used for air conditioner and electronic products.
8021 Aluminum Foil
8021 aluminum foil is the main kind of food packaging, flexible packaging and battery aluminum foils. It has excellent moisture-proof performance, light-shielding and extremely high barrier ability. In addition, it is also non-toxic, tasteless, safe and hygienic.
What’s more, the 8021 aluminum foil surface also has a shiny effect, which can be made into a composite packaging material with many other packaging materials, and the printing effect on the surface of the 8021 aluminum foil is better than other materials.
1060 Aluminum Foil
1060 aluminum foil belongs a pure aluminum foil with the aluminum content of over 99.60%. Therefore, it is of high plasticity, corrosion resistance, electrical conductivity and thermal conductivity. It is widely used in battery, electronics products, capacitor, radiator, aluminum gaskets, automotive heat shields, air condition, food packaging, tobacco,etc.
Haomei, as a big aluminum foil manufacturers, has all these four kinds of aluminum foils. Welcome to tell me the specification your need. We will give you a best price.
Uses of Aluminum Foil
Food Aluminium Foil
Food aluminum foil is of good air tightness, light shading, clean and safe. It can efficiently keep the freshness and fragrance of food. When aluminum foil is used for cooking or barbecuing, it can helps to evenly heat the food to prevent the food from scorching,.
Food aluminum foil price usually depends on the alloy grade, specifications, technical requirements and dosage. The commonly used alloys and tempers are 8011 / H22, 8011 / H24, 8011 / O, and 3003 / H24 aluminum foil. Generally, the price of 3 series aluminum foil is higher than that of 8 series aluminum foil.
Aluminum Food Container
Aluminum food container is a much favored table ware. The thickness of the aluminum food container is generally between 0.03mm and 0.20mm, which can be divided into two types: wrinkled and non-wrinkled.
Its manufacturing process: The 3 or 8 series aluminum ingot is cold or hot rolled into aluminum jumbo roll and then is stamped into the right shape with special equipment and mould.
Battery Aluminum Foil
Aluminum foil is a key material in the positive electrode of lithium batteries. 1 GWh lithium batteries is about 600-800 tons. And the consumption of lithium batteries has been growing quickly in the recent years.
With the rapid development of the lithium battery market, the consumption of aluminium foil jumbo roll for lithium battery in China has been over 80,000 tons in 2020.
Electronic Aluminum Foil
Electronic aluminum foil is a kind of aluminum foil processed by a series of rolling, cleaning and cutting
Electronic aluminum foil is a high-purity aluminum foil , which is made from refined aluminum ingots by hot rolling, and then cold rolled and annealed. Electronic foils mainly include 1/3 series aluminum. Electronic aluminum foils are mainly used in electronic components and other fields.
Aluminum Foil for Capacitor
Making a a capacitor with aluminum foil requires aluminum foil has larger surface area and sufficient bending strength. Aluminum foil capacitor is used for the following equipment:
OA/VA equipment (computer, digital TV, DVD, audio equipment).
Information equipment(mobile phone battery parts, information infrastructure).
Automotive related parts (denso equipment, electric vehicles, hybrid vehicles).
Energy-saving related equipment (frequency conversion appliances).
How to Measure the Thickness of Aluminum Foil
The thickness of aluminum foil for different applications are usually different. According to the thickness, the aluminum foil paper can be divided into light gauge foil and heavy gauge foil. Light gauge foil is about 0.005mm-0.015 mm while the heavy gauge foil is about 0.1～0.2mm. It may a little different in different countries.
How to measure the thickness of aluminum foil? During the production, we need to measure the aluminum foil thickness frequently. Haomei adopts Honeywell thickness gauges to precisely control the thickness of the aluminum foil produced. First-class equipment and state-of-the-art instruments ensure the printing effect and mechanical properties of aluminium foils, and improve the product's packaging performance and temperature resistance performance.
During the use, you also can get the thickness by simple tools, that is, ruler and milligram balance. Use a ruler to measure the length and width of the aluminum foil in centimeters. Crumple the piece of foil into a small ball or fold it into a small shape and place it on a milligram balance to find the weight. Records the values on a sheet of paper. Then make use of the formula to calculate: density = mass ÷ volume.
