China Heat Shield Aluminum Sheet Plate

Heat Shield Aluminum Sheet Plate(1050/3003/3004/5052/5182)
Aluminium Brazing sheet strip foil
The automotive heat exchanger includes radiator, intercooler, oil cooler, condenser and evaporator. The Aluminum Brazing sheet strip foil is the core materials for their production. Aluminum Brazing sheet strip foil is developed with the development of vacuum brazing technology, can brazing in nitrogen atmosphere in the furnace, the technology is characterized in that the requirements of the radiating fin surface of the composite layer brazing alloy, the melting point of the matrix Aluminum Alloy its low 50 ºC, so thermal insulation heat exchanger is arranged on the assembly time good about 600 ºC after the furnace, the fin base alloy melts as Al-Si alloy solder coating melt left after cooling will put them firmly into one brazing.
Composition of Aluminum Brazing sheet strip foil material is composed of matrix Aluminum Alloy one side or both sides of composite brazing alloy has low melting point alloy Al-Si or Al-Si-Zn, the thickness of the coating is usually about 10% of the total thickness of composite materials, (core layer) of the matrix alloy melting point of 630 to 660 ºC, coating the melting point of 577 ~ 610 ºC.
Composite structure:
The composite heat exchange material Aluminum Brazing sheet strip foil can be double layer (base + single layer cortex), three layers (core layer + double layer cortex), four layers (core layer + two layers cortex + one water contact layer), five layers (core layer + upper and lower two layers of cortex).
Automotive cooling composite material is a high-tech product: the thickness of the composite layer should be uniform, the surface without composite layer off, the matrix alloy after brazing, high strength, strong corrosion resistance, good solderability and so on.
The automotive heat exchange materials include composite materials for radiator of water tanks and composite materials used for air conditioning radiators. The tube type radiator is using 2.8KG aluminum compound foil for each vehicle, and the air conditioner uses three layers of composite aluminum alloy foil 4KG/ each.
