Aluminum foil for heat exchangers
Aluminum alloy composite plates, composite strips and composite aluminum foils are collectively referred to as aluminum alloy composite materials. Aluminum alloy composite materials for automobile heat exchangers are mainly made of two or more layers of aluminum alloy by hot composite rolling. The core layer plays the role of strength support and heat dissipation, and the cladding layer mainly plays the role of solder.
Aluminum alloy composite materials are mainly used in automobile water tank radiators and air conditioners. The annual demand is large. With the rapid growth of automobile production and consumption in my country, the demand for this material is increasing, with an annual growth rate of 40%. In addition, , Aluminum alloy composite materials are used in trains, engineering vehicles, special vehicles, refrigerated vehicles, large locomotives, airplanes, air conditioning, oil pressure devices, oxygen generators, air separation devices, hydrocarbon separation devices, natural gas liquefaction and evaporation devices and many other fields Both have a wide range of applications. The difference between composite radiator aluminum foil and ordinary plate and strip foil is that the core material ingot and the rolled coating material need to be prepared separately. The core-skin material pairing is to place the 4XXX series alloy plate on the core material 3003 alloy aluminum billet. They can be welded together or not, if welding can improve the yield. Aluminum alloy composite plates, composite tapes and composite foils are collectively referred to as aluminum alloy composite materials.

The three-layer composite aluminum alloy heat dissipation material for automobile heat exchangers is a key material for manufacturing automobile water tank radiators and automobile air conditioners. Heat sink and water tank high-frequency welded pipe blanks usually use three-layer composite aluminum alloy strip, which is a new high-tech material. The core material of the three-layer composite strip is made of rust-proof aluminum alloy, and the skin material is brazing material coated on both sides of the core material, double-breaded, and made by high-temperature and high-pressure hot-rolling composite rolling. The three-layer composite belt can meet the performance requirements of weight reduction, corrosion resistance, good thermal conductivity, high strength, good processing formability, and brazing ability.
