4343/3003 Aluminum brazing sheet coil strip for radiator fin

The Aluminum brazing sheet coil strip is a multilayered composite sheet, typically encompassing diverse metallic alloys that are seamlessly fused through brazing processes. This method ensures the optimal utilization of the unique properties of each alloy, while satisfying the demanding requirements of high thermal conductivity and corrosion resistance. Consequently, it finds extensive applications in automobiles, construction machinery, power stations, as well as residential and commercial air conditioning heat exchange systems, where heat transfer efficiency and corrosion resistance are paramount.

The utilization of 4343/3003/4045 aluminum brazing plates serves as a prevalent example in the realm of brazed composite materials, particularly in their application as radiator fins. Radiators typically consist of heat pipes, fins, side plates, and motherboards, with the fins systematically arranged in an orderly fashion. This design facilitates the integration of various metal layers, each boasting distinct properties like exceptional thermal conductivity and corrosion resistance, to cater to specific operational demands. Notably, 3003 aluminum serves as the backbone, while 4343 aluminum fulfills the role of brazing clad for CAB applications.
