10 micron Aluminum Foil Price
Formed foil is the product of a special high-purity aluminum foil that has been electrochemically or chemically corroded to enlarge the surface area, and then undergoes electrochemical conversion to form an oxide film (aluminum oxide) on the surface. According to voltage, formed aluminum foil is generally divided into There are four types: extremely low pressure, low pressure, medium high pressure and high pressure. According to the thickness, it ranges from 25-110 microns; according to the purpose, there are positive foil and negative foil, as well as guide foil.
In fact, the use of formed foil is very narrow and can only be used as aluminum electrolytic capacitors. However, the uses of capacitors are very wide.
The aluminum foil used in electrolytic capacitors belongs to the category of electronic aluminum foil, which is a corrosive material that works under polar conditions. Electronic aluminum foils of different polarities require different types of corrosion. The high-voltage anode foil is corroded by column holes, the low-voltage anode foil is corroded in spongy form, and the anode foil in the medium-voltage section is corroded by insects.
High-voltage anode aluminum foil can be divided into two categories, one is high-quality high-voltage aluminum foil; the other is ordinary high-voltage aluminum foil.
The characteristics of high-quality high-voltage anode aluminum foil are "two high and one thin", that is, high purity, high cubic texture and thin surface oxide film. This type of product is of high quality but high cost. Aluminum purity>99.99%, cubic texture 96%. The vacuum heat treatment is carried out under the conditions of 10-3Pa~10-5Pa.
Ordinary high-voltage anode aluminum foil is an economical and practical high-voltage anode aluminum foil, with aluminum purity >99.98%, cubic texture >92%, and vacuum heat treatment is carried out under the conditions of 10-1pa~10-2pa.
The process of low-voltage anode aluminum foil is relatively complicated, and it is considered impossible to adopt a method to meet the requirements of each section of voltage. It can be roughly divided as follows.
For low-voltage aluminum foil less than 35Vf, corrosion of hard high-purity aluminum foil should be developed. The characteristic is that the hard state can provide a large number of corroded small cores and corrosion channels. As for DC corrosion and AC corrosion, which power source is better needs to be studied. The industry believes that the specific volume of this method can be increased by 5μF/cm2 compared with the soft state method.
For low-voltage foils greater than 50Vf, soft high-purity aluminum foils provide conditions for a lot of crystal plane orientation differences, and corroded foils with larger etch holes can be obtained.
Aluminum Foil For Braquettes Different grades of aluminum foil are very effective. For example, fireproof and ordinary are not the same grade.
