PRODUCT DESCRIPTION

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 is an important inorganic fluoride salt with specialized applications in several industrial fields. In aluminum alloy processing, it is used as a flux and refining agent, effectively removing hydrogen gas and oxide inclusions from molten aluminum, thereby improving alloy purity and mechanical properties. In the grinding wheel and abrasive tools industry, it serves as a filler and active additive, enhancing the wear resistance and cutting efficiency of resin-bonded grinding wheels. In brazing applications, it acts as a flux for aluminum and aluminum alloys, effectively removing oxide films and promoting solder flow and wetting. Additionally, it has minor applications in ceramics, glass, and fire-resistant materials. Its advantages include good thermal stability and low hygroscopicity, but attention must be paid to the potential toxicity and corrosiveness of fluorides, requiring proper protective measures during use.
