Potassium hexafluoroaluminate is a white or light gray powder, or a blocky crystal. About 950℃. It will melt into liquid at high temperatures and has a certain degree of fluidity. Slightly soluble in water, its solubility in water increases slightly with the rise in temperature. Insoluble in ethanol. It is stable under normal temperature and pressure and will not decompose easily. However, when exposed to strong acids, a reaction occurs, releasing hydrogen fluoride gas.

Product Usage

Potassium hexafluoroaluminate (Potassium hexafluoroaluminate) has a wide range of applications. In the metallurgical field, it can be used as a flux for the melting and casting of aluminum and aluminum alloys, as well as a substitute or additive for electrolytic aluminum, helping to lower the smelting temperature, remove impurity gases to improve product quality and electrolytic efficiency. In the field of welding, as a brazing flux for aluminum and aluminum alloy welding, it can remove oxide films and enhance the wetting and spreading ability of brazing filler metals, and is suitable for various brazing processes.
