Product Description

4104/3003/4104 aluminum sheet plate for Engineering machinery fin 

 Brazing is a method of joining two pieces of metal together with a third, molten filler metal. Of all the methods available for metal joining, brazing may be the most versatile. The process is relatively fast and economical, requires relatively low temperatures and is highly adaptable to automation and lean manufacturing initiatives.

*Perfect surface condition and tolerance control 
 
*Good consistency for any fin mill
 
*Excellent collapse resistance and strength after brazing
