Potassium fluoroaluminate 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:
1. Production of abrasives: as active filler in resin-bonded abrasives for metal-treatment
2. Production of welding agents: as components in coatings of welding rods and welding powders
3. Production of soldering agents: as component of fluxing agents for soldering of aluminium
