Powder flux for all high silver content brazing alloys
Powder brazing flux for capillar brazing with high silver content alloys. At elevated temperature the flux reduces the metal oxides on the base metal and activates the surface. This results in an optimal wetting of the filler metal and increase of the capillar effect in the gap between the two surfaces to be joined. The development of a surface alloy between the filler metal and the base metal ensures the metallic continuity. The surfactant Armosin helps to obtain an even thickness of the brazing flux, which adheres strongly with the base metal during the heating phase. The brazing operation is easier, this increases the productivity specially for large series of parts. The brazing flux 1802 N Atmosin is designed for use with the following heating methods: oxyacetylenic flame, other oxy-fuel flames, air-fuel flames and furnace without gas protection.
