Tenacity™ No.14 Flux Powder is a brazing flux suitable for use with silver brazing filler metals. It is principally designed for use on brass where red staining, due to oxidation of zinc during heating, is a problem. It is active at about 450°C and spreads rapidly giving good cover early in the heating cycle. It is recommended for use with silver brazing alloys that melt below 700°C. JM special purpose fluxes are required when brazing aluminum bronze or where protracted heating is involved.Information provided by Johnson Matthey Metal Joining |
