Main Application:

1.Potassium Aluminum fluoride is used as fluxing agentin the smelting of secondary aluminium to maximize metal recovery, to remove the magnesium content of liquid aluminium alloys.
2.Potassium fluoroaluminate can used as brazing flux in aluminum alumium alloy and stainless steelt.
3.Potasium Cryolite cam sed as additive agent for produce grinding wheels or other abrasive products.
4.KAlF4 is a common additive to roofing shingles as an alkaline Ph adjuster and as color additive to coatings
5.Glass producers use the PAF for opacification, or to cloud the glass giving it a milky white color. 
6.Used as an insecticide

 

For Abrasive Application

Potassium Aluminum Fluoreide is widely used as an active filler in organic binders (using resin, rubber or shellac as binders) in grinding wheels and abrasive belts. And the use of potassium fluoroaluminate plays an important role in the abrasive, the specific performance in the following areas:
1.Potassium Aluminum Fluoride can improve the cutting / grinding performance, the low melting point of the passivation has been conducive to the shedding of abrasive particles, thereby enhancing the efficiency of the use of other abrasive particles. Specific performance of the unit to improve the cutting speed per unit time, or reduce the surface area per unit abrasive wear.
2.Potassium fluoroaluminate can improve the cooling performance, reduce abrasive fever produced by burns or deformation.
3. Potassium Cryolite will precipitate fluoride ions in the grinding process, corrosion of metal, a greater degree of strengthening the grinding function.
4. PAF content fluoride characteristics, can prevent the grinding surface transition oxidation.
5.As a binder in the reinforcement material, improve the strength and wear resistance of the binder.
6. PAF to extend the service life of abrasive.
