Harris ESF250PB HIGH TEMP Flux Paste 250gm

Harris ESF250PB High Temp is a unique 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 helps 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).

Features:

• Boric Acid and Borax free – Environmentally friendly
• Homogeneous mix that stays in solution or suspended paste
• Dissolves surface oxides and protects against oxidation during heating
• Wide activation range
• Excellent flux coverage during heating
• Easy flux residue removal
• 250gm
