Tenacity 5 Flux Powder

Tenacity™ No.5 Flux Powder is a brazing flux suitable for use with silver brazing filler metals. It is active at 600˚C and is effective with alloys that melt below 850˚C. Tenacity™ No.5 shows good overheat resistance when compared to other silver brazing fluxes. This characteristic is useful when brazing stainless steel components for example, where because of its poor thermal conductivity there is a risk of overheating causing the flux to become exhausted and ineffective. 

Tenacity™ No.5 also shows an extended life at brazing temperature (time / temperature stability). This feature is important when brazing large assemblies in steel or copper for example, or wherever prolonged heating is necessary
