Flux - Powder, Tenacity 125 (for High Temperatures)

Tenacity 125 - Flux Powder - For High Temperatures - Flux

Johnson Matthey Metal Joining Tenacity™ No. 125 Flux Powder constantly evolves to meet the needs of its customers, of emerging technologies and of the environment it operates in.

Tenacity™ No.125 Flux Powder is a high temperature flux that is effective on platinum, copper, copper based alloys, mild and low alloy steels and tungsten carbide with brazing filler metals melting between 750-1150°C.
Typically it would be used with specialized JM Bronze™ or Argentel™ Alloys, particularly F-Bronze.

  • Product uses: Tenacity™ No.125 Flux Powder is suitable for use on platinum, copper, copper based alloys, mild and low alloy steels and tungsten carbide.

  • Conditions for use: The powder should be mixed with water and a few drops of a liquid detergent to form a paste which should then be brushed onto the joint surfaces before assembly. Further flux should then be applied externally either side of the joint mouth.

It is good practice to mechanically clean and degrease the joint surface before applying flux.
Heat slowly and evenly to the brazing temperature, without local overheating.
If blackening of the flux occurs this is often a sign of insufficient flux, overheating or flux exhaustion.

How to use…
1. Mechanically clean and degrease the joint surface before applying flux
2. Mix flux powder with water and a few drops of liquid detergent to form a thick paste
3. Brush paste onto the joint surfaces before assembly and externally either side of the joint opening
4. Heat evenly to the brazing temperature, avoid localised overheating
5. If blackening of the component or flux occurs this is a sign of insufficient flux, overheating or flux exhaustion
6. The flux residues are insoluble in water and must be removed by mechanical methods such as filing abrasives and grit blasting
