Chamber furnace CuproBraze®

The CuproBraze process is a brazing process specifically developed for the manufacturing of automotive and heavy-duty industrial heat exchangers. By using high strength copper alloys it is possible to manu-facture light, strong, efficient and compact heat exchangers at a low cost with this envi-ronmentally friendly, lead-free process. The brazing of CwproBraze* radiators uses a non-toxic low temperature melting alloy that works well in a nitrogen based controlled atmosphere furnace. The brazing material is lead free and there is no post-braze treatment required, such as rinsing. Binders and braze alloys can be applied to the tubes, fin tips or headers by spraying, brushing or rolling. After brazing, the brazed copper-brass joints are significantly stronger than the solder metal and do not suffer from galvanic corrosion. Developed for this process, anneal resistant header, fin and tube materials assure the strength of the products.
