Soldering of copper and copper alloys strong pickling flux

PROTINFLUX 1009 - Soldering of copper and copper alloys strong pickling flux

PROTINFLUX 1009 has a great pickling power. Its wettability is excellent, the eutectic is minimised as much as possible. The flux is stable at high temperature, even with flame heating.
Mineral flux 1009 is highly concentrated, is safe to use and generates good cost savings.

PRODUCT APPLICATIONS

PROTINFLUX 1009 is intended for the preparation of copper alloys for brazing processes using lead/tin) or lead/tin/silver (low silver content) filler metals.

DIRECTIONS FOR USE

The pieces are fluxed by dipping, spraying or hand brushing them. The brazing is done either in a furnace, by torch soldering or by dipping in a tinning bath

GENERAL USAGE CONCENTRATIONS
  • Core brazing : 5 to 20% in water
  • Torch soldering : 30% in water
  • Collector brazing : 30% in water

The control of the fluxing bath is done by checking its density.
The brazing is followed by rinsing in water and then washing with acid to remove any residual salts which could cause corrosion.
