Prolonged Heating Silver Brazing Flux Tenacity 5a from Johnson Matthey - 500g pot
Tenacity™ No.5a Flux Powder is a brazing flux suitable for use with stainless steel
Tenacity #5a is active at 600C and is effective with alloys that melt below 850C.
Tenacity™ No.5a shows good overheat resistance when compared to other brazing fluxes. It is this characteristic which makes Tenacity 5a 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.5a 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.
