welding flux uses of high quality Potassium Cryolite price KAlF4 in aluminum alloy

welding flux uses of high quality Potassium Cryolite price KAlF4 in aluminum alloy

From the reaction of anhydrous hydrofluoric acid and aluminum hydroxide to produce fluoroaluminate, then react with potassium hydroxide at high temperature, filter, dry, melt and crush. It can also be prepared by the reaction of aluminum fluoride, ammonium fluoride and potassium chloride.

Used as an insecticide, also used in ceramics, glass industry and aluminum brazing.

Used as aluminum alloy industry flux, and aluminum alloy magnesium removing. 

Used for abrasive tools. 

Used for glass casting. 

Potassium fluoroaluminate
Potassium fluoroaluminate (KalF4) is used for the production of welding agents, the production of soldering agents and for the production of abrasives.
Potassium fluoroaluminate is used in the the following applications:
Production of abrasives:
as active filler in resin-bonded abrasives for metal-treatment
Production of welding agents:
as components in coatings of welding rods and welding powders
Production of soldering agents:
as component of fluxing agents for soldering of aluminium
