Characteristics of 1070 aluminum foil

  • 1. Conductivity. The conductivity of 1070 aluminum foil is as high as 62{20℃(68℉)(%IACS)}, which gives it a strong conductive advantage over other alloy aluminum foils. The thermal conductivity and electrical conductivity of 1070 aluminum alloy foil are second only to copper, silver and gold.
  • 2. Good corrosion resistance. Similarly, the surface of 1070 aluminum foil without special treatment will naturally produce a dense Al2O3 protective layer, which has good corrosion resistance to the atmosphere (including industrial atmosphere and marine atmosphere), water, most acids and organic matter.
  • 3. Light weight. Under the same volume, the weight of 1070 aluminum foil is only about 35% of Cu and Fe.
  • 4. Other features. In addition, 1070 aluminum foil also has good ductility and formability. Below 0°C, the lower the temperature, the higher the strength and plasticity.

Applications of 1070 aluminum foil

1070 aluminum foil for electrolytic capacitors

1070 aluminum foil has a high electrical conductivity of up to 65.0% IACS, as well as excellent thermal conductivity and corrosion resistance, which can well meet the performance requirements of aluminum foil for electrolytic capacitors. It is worth mentioning that Huawei 1070 aluminum foil for electrolysis has stable performance and guaranteed quality. It is used in electronic foils such as capacitors, with a market share of more than 80%.

1070 aluminum foil for transformer

The use of 1070 O aluminium foils strips for transformers winding is the most important material in transformer manufacturing.

The quality of aluminum foil directly affects the performance of transformers.

So in the production process, we should pay attention to some details. Here are some benefits of 1070 O aluminium foils strips for transformers winding:

  • 1.The surface of 1070 O aluminium foils strips for transformers winding is extremely smooth, and there will be no burr or scratches on it. This greatly reduces the chances of short circuit between windings.
  • 2.The 1070 O aluminium foils strips for transformers winding can be cut arbitrarily during processing without generating sparks, so that it will not affect the safety of operation.
  • 3.1070 O aluminium foils strips for transformers winding is soft, which can reduce the stress caused by bending deformation and improve its mechanical strength to prevent cracking or breaking of the coil during bending and installation.
  • 4.The 1070 O aluminium foils strips for transformers winding has good electrical conductivity, low resistivity, which can reduce energy loss and enhance power efficiency in the process of power transmission and distribution.
  • 5.High reflectivity: According to statistics, more than 97% of aluminum foil reflects infrared light.

1070 cosmetic cover aluminum foil

Cosmetic bottle caps commonly use 0.17mm to 0.5mm thick 1070 aluminum foil. The strength, elongation and dimensional deviation of the 1070 aluminum foil used in Huawei cosmetic bottle caps are strictly and effectively controlled. The produced 1070 aluminum foil is flat and has no curl marks, scratches or stains, ensuring bottle cap shaping, post-adhesive and other processing Require. – Printing is satisfied.
