fluxing agent steel mills

  • Why is flux required when brazing brass and not required

    A fluxing agent (or a controlled atmosphere as found in furnace brazing) is required for all brazing and soldering applications. The purpose of the flux is to remove oxides from the base material and to prevent oxidation during the heating process thus promoting the free flow of the brazing filler metal.
