Alu. Brazing Sheet

Aluminum Brazing Sheet

For Brazed Automobile Heat Exchangers
 
Cladding an aluminum-silicon alloy with a brazing sheet provides an aluminum alloy that has the thin walls necessary for use in automobile heat exchangers, as well as such desirable characteristics as high strength, corrosion resistance and formability. We have developed and are refining a variety of products of this sort.
