Tenacity™ No.5 Flux Powder is a brazing flux suitable for use with silver brazing filler metals. It is active at 600C and is effective with alloys which melt below 850C.

Product uses:It is particularly recommended for brazing stainless steel at temperatures above 700C and also for brazing large assemblies in steel or copper wherever prolonged heating is necessary.

Conditions for use:Tenacity™ No. 5 flux powder should be mixed with water and a few drops of liquid detergent to form a thick paste. 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. Use the flux as a temperature guide - it will become clear or opaque as brazing temperature is approached. If blackening of the flux occurs this is often a sign of insufficient flux overheating or flux exhaustion.
