Product Description

4343/3003/4343 aluminum sheet plate for Evaporator fin 

The most important brazing method for aluminium is furnace brazing (in particular for the production of heat exchangers). But the traditional aluminium brazing techniques like dip (flux) brazing and manual flame (torch) brazing still find their specific applications. In contrast to manual flame brazing, industrial brazing techniques such as dip and furnace brazing require fairly large capital investment and sophisticated production control systems.

*Perfect property for fine stamping 
 
*Good consistency for any fin mill 
 
*Excellent collapse resistance and strength after brazing
