Gasflux® works extremely well with copper-base silver brazing alloys. These include phos-copper, copper-phos-silver( 0-15%) as well as higher-silver content alloys (30-56%). The Gasflux® flame, when used in conjunction with silver-brazing alloys, provides a protective shroud around the area to be joined which will prevent the formation of unwanted oxides. The additional wetting action provided by Gasflux® assures high quality joints with less alloy required along with a reduction of leaks.
