Potassium Aluminum Fluoride (KAlF4) is a commercial grade fused solid, inorganic salt. The material serves as an alternative to conventional fluoride salts for a variety of applications, a few of which are listed below.

The size can be:1-3mm, 20, 40, 100, 200 and 325mesh. It is composed by KF-AlF3, Molecular rate near 1.2, melting point 557-580. Solubility in 1000g water: at 0: 0.8g; at 25: 1.42g, at 100: 4.58g.

Packing:

In 25kgs plastic woven bag lined with high-pressure plastic film, or according to customer's requirements.

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
