Aluminum foil for transformer is mainly used for small and medium-sized transformers with a capacity of less than 2000kVA. Its advantages are that it can increase the filling factor of the conductive material in the iron window, reduce the volume, and increase the radial thermal conductivity of the winding, with low temperature gradient and good thermal stability, thereby suppressing the hot spot temperature of the winding.
Battery aluminum foil has the characteristics of good conductivity, soft texture, cost advantage, stable performance under high potential and not easy to oxidize, and the above characteristics are well adapted to the requirements of power batteries for current collectors. At present, the battery aluminum foil produced in the market is mainly 1060, 1070, 1100, 1235 and other alloys, and the above alloys belong to the 1000 series.
Air conditioning foil is a special material for manufacturing heat exchanger fins for air conditioners. The air conditioning foil used in the early days was plain foil. In order to improve the surface performance of plain foil, coated aluminum foil is to reprocess the surface of non-coated aluminum foil to give it some special functions. Before forming, it is coated with an anti-corrosion inorganic coating and a hydrophilic organic coating to form a hydrophilic foil. At present, hydrophilic aluminum foil accounts for 50% of the total amount of air conditioning foil, and its use ratio will be further increased.
Aluminum foil flexible tube is a kind of pipe widely used in various fields and has many common uses. In terms of ventilation and air exchange, aluminum foil hose has better ventilation performance, can effectively transmit air, and keep indoor air fresh and circulated. In some special occasions, such as places with high fire protection requirements, the fire protection performance of aluminum foil hose is obviously superior.
Aluminium foil capacitor is a kind of aluminum foil made by a series of rolling, cleaning and cutting processes on high-purity aluminum ingots. It is often used in electronic components. Electronic aluminum foil is mostly high-purity aluminum foil, such as 1070 aluminum foil, 1100 aluminum foil, etc. It has good electrical and thermal conductivity and is a common material for electrolytic capacitors.
