8011 aluminum foil is a more common type in the 8000 series. In addition to being used as a packaging material for pharmaceutical products, it is also a raw material for making household foil.
Why is 8011 grade aluminum foil suitable for household foil?
Material composition and properties
8011 aluminum is part of the 8000 series aluminum alloy, which is characterized by excellent performance in foil applications. Its composition usually includes:
Aluminum (Al): about 98%
Iron (Fe): 0.6% to 1.0%
Silicon (Si): 0.5% to 0.8%
Trace elements: including copper (Cu), manganese (Mn), zinc (Zn), magnesium (Mg) and titanium (Ti).
The fact that 8011 aluminum foil can be used as a raw material for household foil is also closely related to its own good properties.
Key features of 8011 aluminum foil
Density: 2.71 g/cm³ (similar to other aluminum alloys)
Tensile strength: 105-145 MPa, depending on tempering
Yield strength: 85-120 MPa
Thickness: 0.006 mm to 0.2 mm for household use
Melting point: about 660°C (1220°F)
Excellent ductility and forgeability of 8011
A major feature of 8011 aluminum foil is its ductility and forgeability. These properties allow it to be easily rolled into thin sheets without cracking. This is critical for household aluminum foil, which needs to be thin, flexible, and able to wrap a variety of shapes and items without tearing.
Good barrier properties of Aluminum 8011
8011 aluminum foil is an effective barrier to moisture, light, oxygen, and contaminants, making it ideal for packaging food. The impermeability of aluminum foil helps keep food fresh, prevent spoilage, and extend shelf life.
8011 foil is non-toxic and food safe
8011 foil is non-toxic, tasteless, odorless, and safe for direct contact with food. It does not react with most foods, thus preserving their flavor and aroma. It also resists bacteria and microorganisms, adding an extra layer of safety to food storage and handling.
8011 alu foil is highly reflective
The shiny, reflective surface of 8011 foil offers two significant advantages:
Heat reflection: reflects up to 98% of radiated heat, which is useful for cooking applications that require heat retention.
Light barrier: protects light-sensitive foods from spoiling due to UV exposure.
Lightweight and cost-effective
8011 foil is lightweight, making it easy to handle and store. In addition, its relatively low production cost makes it an economical choice for home use compared to other packaging materials. This affordability is one of the reasons why it is so popular in everyday kitchens around the world.
