Harris ESF250PB HIGH TEMP Flux Paste 250gm
Harris ESF250PB High Temp is a unique, patent-pending flux that is designed to handle high heat when it is time to braze.
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.
Features:
- Boric Acid and Borax free – Environmentally friendly
- Homogeneous mix that stays in solution or suspended paste
- Powder flux has excellent adherence when the heated rod is dipped into this flux
- Dissolves surface oxides and protects against oxidation during heating
- Wide activation range
- Excellent flux coverage during heating
- Easy flux residue removal
