Product Description

4343/3003/4343 Clad aluminum strip fin material for condenser

The Signi's fin material can be used in various types of exchanger, with good performance for the follow-up product processing (fin forming, brazing) , it has the good stability in brazing process, and can be used for big machining windows. After the brazing, the coarser grain is formed, with high strength, excellent anti-collapse performance advantages.
 
 


The coarse grains is formed after the brazing, it can significantly improve the anti-collapse performance, and for the clad fin material, it can reduce the penetration of the clad to the core, in the entire brazing process to keep the shape , forming a good weld.
