Potassium Fluoroaluminate Product Introduction

Potassium fluoroaluminate (chemical formula: $KAlF_4$ or $K_3AlF_6$ complex), commonly known as an inorganic flux or aluminum flux, is a widely used white inorganic salt in industrial applications. Due to its excellent physicochemical properties, it has become an indispensable auxiliary material in modern industrial production.

The primary application of potassium fluoroaluminate is in aluminum brazing. As a highly effective flux, it effectively removes the oxide film from the surface of aluminum alloys, lowers the melting point, and improves the wettability of the molten solder, thereby achieving high-strength metal connections. In addition, it is often used as a magnesium removal agent in the aluminum processing industry, significantly improving the purity of the alloy.

• Appearance: White or light gray powder.
• Low melting point: It has a low initial crystallization temperature, allowing it to melt quickly and function effectively during the brazing process.
• Solubility: Slightly soluble in water, and exhibits strong ability to dissolve metal oxides in the molten state.
• Stability: Chemically stable in a dry environment, facilitating long-term storage and transportation.

• Abrasives: As a filler in grinding wheels and sandpaper, it effectively reduces grinding temperature, improves wear resistance and cutting efficiency.
• Glass and ceramics: Used as a flux in production to reduce firing costs.
• Pyrotechnics: Used in the manufacture of luminous agents.
