Overview of aluminum foil for electronic products

As one of the core materials of electronic devices, aluminum foil for electronic products has always been the focus of electrical appliance manufacturers. As a term that doesn’t come up very often, you might have questions about it. What is aluminum foil for electronic products? What are the classifications of aluminum foil for electronic products? What are the applications of aluminum foil for electronic products?

What is aluminum foil for electronic products?

Suffering from the increase of market demand for brand spanking new power automobiles, there is a strong call for for aluminum foil for energy batteries. A few aluminum foil producers declare that the contemporary aluminum foil processing price has expanded by way of 10% over the same period final yr. Power batteries are a hastily growing emerging discipline on the industrial chain and business development tune. As the tremendous contemporary collector of lithium-ion battery rechargeable batteries, cashing in on the acceleration of the global electrification of recent energy motors, the price of aluminum foil for electronic products is likewise rising hastily.

Aluminum foil for electronic products is processed from aluminum fabric into aluminum foil, and then subjected to floor corrosion treatment and oxidation remedy, and then winding processing, and subsequently made into a capacitor. Aluminum foil for electronic products is the important thing raw fabric for the manufacturing of aluminum electrolytic capacitors. Due to the order of the manufacturing process, it is divided into Aluminum foil for electronic products and electrode foil. Electrode foil includes corrosion foil and activation foil.

Common alloys for electronic aluminum foil

Since electronic aluminum foil has high requirements on its conductivity during use, electronic aluminum foil is mostly made of 1000 series aluminum alloy, mainly including:

  • 1050 aluminum foil
  • 1060 aluminum foil
  • 1070 aluminum foil
  • 1100 aluminum foil
  • 1235 aluminum foil

Aluminum foil parameters for electronics

Alloy: 1050, 1060, 1070, 1100, 1235, 3003, etc.

Status: H18, soft H2O (h0).

High voltage anode foil: thickness 0.065mm to 0.1mm.

Low voltage anode foil: thickness 0.06mm to 0.1mm.

Cathode foil: 0.015mm to 0.06mm thick

Aluminum foil for electronic products production process

Aluminum foil for electronic products is a type of aluminum foil processed via a series of techniques which include rolling, cleansing, and slicing of excessive-purity aluminum ingots.

Aluminum foil for electronic products is a refined product manufactured from high-purity aluminum foil. Warm-rolled subtle aluminum (high-purity aluminum) into the aluminum plate, after which solid with the aid of bloodless rolling and annealing procedure. The manufacturing process of aluminum foil for electronic products consists of casting-soaking-warm rolling-pre-annealing-cold rolling-intermediate annealing-cold rolling-foil rolling-slitting-overall performance checking out-packaging.

Classification of aluminum foil for electronic products

Aluminum foil for electronic products can be divided into excessive-voltage anode foil, low-voltage anode foil, and negative electrode foil. The high-voltage anode foil is corroded with the aid of column holes, the low-voltage anode foil is corroded in spongy form, and the anode foil in the medium-voltage segment is corroded via insects.

High-voltage anode foil may be divided into classes, one is remarkable excessive-voltage foil; the opposite is regular high-voltage foil. The traits of terrific high-voltage anode foil are “two excessive and one skinny”, this is, high purity, excessive cubic texture and skinny floor oxide film. This form of product has high first-class but high fee. Aluminum purity is extra than 99.99%, cubic texture is 96%, and vacuum warmth remedy is accomplished beneath the situations of 10-3Pa~10-5Pa. Normal excessive-voltage anode foil is a cost-effective and realistic excessive-voltage anode foil, with aluminum purity> 99.98%, cubic texture> ninety two%, and vacuum warmness treatment is finished beneath the conditions of 10-1pa~10-2pa.

The poor electrode foil can be divided into smooth state and difficult kingdom. Japan is ruled by using tender electrochemical corrosion, and Western Europe is ruled with the aid of hard chemical corrosion. Both have their personal advantages and downsides. The tender state uses high-purity aluminum foil (>99.Eighty five%), that is copper-unfastened and excessive in nice, however the price is likewise excessive; the hard state uses low-purity copper-containing aluminum foil, that is low in price.

Applications of electronic aluminum foil

According to the end user, it can be divided into

  • Aluminum foil for batteries (battery cells, lithium battery electrodes, battery negative electrodes, battery packs, etc.)
  • Aluminum foil for capacitors
  • Aluminum foil for LED (LED bulbs, LED substrates, etc.)
  • Aluminum foil for air conditioning
