Air conditioning foil is the special information for making heat exchanger fin for air conditioner. The early use of air conditioning foil is plain foil. To improve the external performance of the plain foil, an anti-corrosive inorganic coating and a hydrophilic organic coating are applied before forming to form a hydrophilic foil. At present, hydrophilic foil accounts for% & amp of air conditioning foil, and its application proportion will be further improved. There is a kind of water foil, so that the fin has the appearance of water function, avoid condensation water adhesion. The air-conditioning foil thickness is 0.1mm~0.15mm. With the development of skills, air conditioning foil has a further thinning trend, Japan today’s leading product thickness is 0.09mm. In an extremely thin state, aluminum foil should have good formability, its arrangement and performance is necessary to be uniform, less metallurgical defects, less anisotropy, together need high strength, good ductility, uniform thickness, good smoothness.
