ULTRA BLACK FLUX

Product Overview

Ultra Black Flux is a low spattering water based, boron bearing active flux which is used in open air brazing for both ferrous and non-ferrous metals to promote oxide removal. Due to its boron content, Ultra Black Flux is particularly well suited for removing refractory oxides such as chromium and tungsten, i.e. oxides found on stainless steel and tungsten oxide, as well as extended heating cycles where a standard white brazing flux may become saturated.
  • Good part adhesion
  • More effective on stainless steel and carbides
  • Low spattering
  • Made in USA

Typical Industry Applications:

Low temperature silver braze alloys (1100F-1700F), stainless steel, carbides
