Cu-Al flux cored brazing ring

未标题-1.jpg

The outer layer of the Cu-Al flux-cored brazing material is Zn-Al alloy and the inner layer is a composite brazing material composed of white fluoride flux. The white flux is non hygroscopic, non corrosive and does not need to be cleaned after brazing. At present, it is mainly used in flame brazing, high frequency induction brazing and furnace brazing with copper and aluminum alloy, brass and aluminum alloy, aluminum alloy and aluminum alloy.


Refrigeration industry


FC22S and FC20S contain high-purity cesium fluoride flux, which is non corrosive and highly active, and can effectively remove oxide on the surface of copper tube and aluminum tube. Flux cored wire mainly has three forms:disk, strip and ring. It is the ideal material for brazing copper and aluminum tubes.
