Aluminum foil for aluminum electrolytic capacitors are mainly used in the production of aluminum electrolytic capacitors. 1070 aluminum foil is used for this purpose. The main functions of capacitors in electronic circuits are: passing AC, blocking DC, and having the functions of filtering, bypassing, coupling, and fast charging and discharging.
Aluminum electrolytic capacitors have the characteristics of small size, large storage capacity, and high cost performance. They are widely used in many application fields such as consumer electronics, industrial control, mobile communications, new energy vehicles, wind power and photovoltaics, aerospace, etc.
The new energy field will become the main driving force for the growth of the aluminum electrolytic capacitor market. Aluminum electrolytic capacitors used in photovoltaics, wind power, new energy vehicles and other fields are developing in the direction of high specific capacitance, high voltage and high performance. At the same time, as consumers' demand for easy portability, high stability and long life of terminal electronic and electrical products becomes more and more obvious, the matching high specific capacitance, high strength and low leakage performance have become the future development direction. Therefore, with the continuous upgrading of traditional industries and the development of new energy and 5G communication emerging industries, high specific capacitance, high voltage and high performance have become the future development direction of aluminum foil for aluminum electrolytic capacitors.
Due to its high purity, 1070 aluminum has excellent electrical conductivity and is suitable for electrical appliances, electronics and other fields. It is one of the common alloys for producting battery aluminum foil.
1070 aluminum alloy has excellent corrosion resistance and is suitable for applications requiring high corrosion resistance.
Compared with other series of aluminum alloys, 1070 aluminum alloy has lower strength and is mainly suitable for applications that do not require high strength.
1070 aluminum alloy can usually be delivered in the following tempers:
1. O temper: The unheat-treated temper of 1070 aluminum alloy. The 1070 aluminum in O temper has high plasticity and machinability, but relatively low strength.
2. H12, H14, H16, H18 tempers: H12 state is the state after a certain degree of cold working, with a certain hardness and strength. H14 state is harder than H12 state, and by analogy, H16 and H18 states have higher hardness and strength.
