181 PF Atmosin

Heavy duty flux for production and repair work of steels.

Paste brazing flux for capillary brazing with silver containing 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 capillary 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 Atmosin 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 181 PF Atmosin is designed for use with the following heating methods: oxyacetylenic flame, other oxy-fuel flames, air-fuel flames and furnace without gas protection.
