Introduction of Brazing Aluminum Sheet Coil Strip

Brazing aluminum sheet is also called aluminum alloy brazing sheet, aluminum brazing sheet, aluminum brazing composite sheet, aluminum brazing cladding sheet, etc., which belongs to a kind of aluminum sheet commonly used in industrial production. The main products of brazed aluminum sheets are 3xxx and 4xxx series aluminum alloy sheets. Brazed aluminum sheets are used in the fields of radiators for electronic appliances and automobile industry, such as: air conditioner condensers, radiators, radiators for electronic components, etc. Commonly used alloys for brazing aluminum plates coils strips are: 4045/3003, 4343/3003, 4045/3003/4045, 4343/3003/4343, 4343/3003/7072 and etc.

Flait Aluminum uses surface pretreatment process to mill the base/core alloys and cladding layer alloys ingots to ensure that there are no defects such as deep grooves, aluminum chips, slag inclusions, surface cracks, etc., and use physical and chemical methods to strictly clean the oil, dust and metal oxide film on the surface of the aluminum plate. Under the premise of ensuring the product quality, the aluminum brazing cladding sheet produced has no pores, cracks, welding tumors, etc., and has a bright surface, uniform weld and beautiful appearance.
