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
