Product Description

flux additive for Aluminium alloy fluxing agent Potassium Cryolite K3AlF4


Appearance: White Powder
Melting Point:1025℃

Properties: White or light gray powder,slight soluble in water.It can react with water to release hydrogen fluoride at high temperature,may be slowly dissolved in acid to release hydrogen fluoride.Its melting point is 560 degrees.

Potassium aluminium fluoride is an inorganic compound.
This compound is used as flux in the smelting of secondary aluminium, to reduce or remove the magnesium content of the melt. The main environmental issue that arises from using PAF is the production of fluoride gases. Calcium hydroxide is widely used to suppress the fluorides produced but in most cases fails to remove it sufficiently.
PAF is also present in a wide range of products for the metals industry as a fluxing agent within additives to help its dispersion within a charge.
It is also used as an insecticide.




1. It is used directly in magnesium rich aluminium alloys to remove and control of magnesium in the aluminium alloys. It is much safer in this applications where earlier Chlorine gas were used, these gases cause local health problems and are also responsible for ozone depletion.
2. It is used in the manufacture of grinding wheels (filler/binder) and other abrasive products.
3. Other common applications of PAF are as additive to roofing shingles, where it acts as an alkaline Ph adjuster and flame retardant. It can also be used as color additive to the coatings for roofing granules.
4. Glass producers use the PAF for opacification, or to cloud the glass giving it a milky white color.
