What is extra thick aluminium foil sheet

  Speaking of aluminium foil thickness, we think of 0.09mm or 0.1mm. Usually foil aluminium is not over 0.2mm thick, but there are thick aluminium foil sheet and even extra thick aluminium foil rolls. And the usage are quite familiar to us: transformer winding and sealing liners.

  Transformer aluminium foil rolls mainly refer to aluminium strip 1060. While being used for transformers, it is an extra thick aluminium foil, with a thickness between 0.2mm and 3mm. 1060 O aluminium foil is used for winding units of high and low voltage in dry type transformers to achieve conversion and impedance matching between different voltages (currents). The traditional winding material for transformers is copper, which is much more expensive. People have been looking for an alternative of copper. The conductivity of metals are successively silver, copper, gold, aluminium, nickle and steel. Since the conductivity of aluminium is only second to copper, it becomes the best alternative as a transformer winding material. But the requirements for transformer aluminium foils are really high, and only powerful suppliers are able to supply them.

  In addition to 1060 extra thick aluminium foil sheet, there is thick aluminium foil sheet, too. Take 8011 aluminium foil used for sealing liners for example. A roll of 8011 foil aluminium can be as thin as 0.016, but thick ones reach 0.5mm thick. Both thicknesses can be used as sealing liner materials, but in varied application conditions. Thick aluminium foil sheet products have natural advantages in sealing bottles and other containers. They display an excellent insulation property, protecting sealed materials (food, medicine, make up etc.) from moisture, gases, smells etc, keeping them fresh as long as the liners are not removed.

Application of thick aluminium foil sheet in specifications

Aluminum (Al) is a silvery white, soft, ductile metal that is the third most abundant element (after oxygen and silicon) and makes up about 8% by weight of the Earth’s crust. Aluminum is so chemically reactive that native specimens are rare. Instead, it is found combined in over 270 different minerals. The primary ore used in the production of aluminum metal is bauxite.

Aluminum is remarkable for its light weight, strength, durability and for its ability to resist corrosion, due to the formation of an extremely thin yet very strong layer of oxide film. Structural components made from aluminum and its alloys are vital to the aerospace industry, transportation, building construction, and many other industries and applications.

Aluminum foil is widely used in packaging, insulation, and electromagnetic shielding. Aluminum sheet is used to manufacture vehicle bodies, home appliances, siding, cookware, and in thousands of industrial applications where a strong, light, easily formed material is needed.

Comprehensive advantages of aluminum foil containers and food packing

The comprehensive advantages of aluminum foil containers and food packing:

1. aluminum foil material is non-toxic, quality and safety.

Aluminum foil is made of primary aluminium alloy and rolled through many processes. It has no harmful substances such as heavy metals. Therefore, aluminum foil can be safely contacted with food, and it will not accommodate or help bacteria grow. In most cases, aluminum foil does not react with food. On the market, a considerable number of plastic lunch boxes are manufactured from unknown raw materials, even fake and waste plastics, which makes it difficult to guarantee the quality and reliability.
