BlackBand Flux for Zinc & Cast Iron

BlackBand is a water based flux containing zinc chloride and other active salts, which will provide an extremely effective fluxing reaction on both ferrous and non-ferrous alloys at typical soft soldering temperatures. Black Band is commonly used for soldering copper and brasses but will work well on mild steel automotive body work applications and applying solder coatings in conjunction with tinning compounds on cast iron fabrications. Traditionally Black Band has been used in a wide variety of industrial soldering applications such as copper-brass heat exchangers which would use gas torches to facilitate the heating process.

This product has a shelf life of 36 months from the date of manufacture.

Key Products Features & Benefits: 

  • High activity flux – effective soft soldering of copper, brass, mild steel and iron.
