High Temperature or Prolonged Temperature Silver Solder Flux
Description: Boric Acid-free Brazing Flux, contains no Sodium-Borate salts.
Active Change: High Heat: 565°C - 982°C The world’s first boric acid-free smart flux.
For Silver Soldering: steel, stainless steel, Monel®, nickel, copper, brass, bronze and other ferrous and non-ferrous metals and alloys. High Heat flux is designed to extend the temperature and life of the flux. This is helpful during longer part heating cycles, or in cases of intense localized heating, such as induction brazing. Extremely fluid. Will penetrate the tightest joints. Not subject to recrystallization (lumpiness-hardening). May be water thinned.
