Application: 

The Potassium Fluoroborate can be used as abrasives for thermosetting resin grinding wheels, raw materials for boron-containing alloys, fluxes for heat welding and brazing, and components for low chromium anhydride chrome plating and lead-tin alloy electrolytes.

Used as analytical reagents and fluxes, also in the manufacture of boron trifluoride, molds for aluminum and magnesium casting, electrochemical engineering and chemical testing.

Used as a flux for heat welding and brazing, aluminum-magnesium casting produces raw materials containing boron alloys and is used as a filler in heavy-duty grinding wheels using resin as an abrasive binder. When welding and fusing silver, gold, and stainless steel, the residue of light metals can be cleaned. It is a raw material for the production of boron trifluoride and other fluoride salts. 

Used as a fluxing agent in welding and as a raw material for the manufacture of other fluoride salts, the Potassium Fluoroborate can also be used in electrochemical processes and reagents.

Resin finishing agent for textile printing and dyeing, metal particle size improver for non-ferrous metals and refining flux, aluminum and magnesium alloy casting grit.
