It is effective on copper and copper based alloys, mild and low alloy steels and tungsten carbide.


Stir the paste before using it .The paste 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.
