Product Description

Aluminium clad strip for tube/automotive radiator (4343/3003/7072)

The Signi's tube material can be used in various types of heat exchanger, with good performance for the follow-up product processing , it has the good stability in brazing process, the coarser grain is formed, after the brazing, with high strength, excellent anti-collapse performance advantages.
 
The coarsegrain, after brazing, can significantly improve the resistance to corrosion, the composition of the material is very important for the strength of the welding , and for corrosion resistance.
