High-Purity Fine Chemical Product
Potassium Hexafluoroaluminate is the high-purity form of potassium cryolite. Its chemical composition is K₃AlF₆. This product has higher potassium content than KAlF₄. It also has a larger fluorine-to-aluminum ratio. These properties give it different physical and chemical characteristics in high-temperature processes. It is widely used in high-end abrasives, special fluxes, and functional materials.
Yunnan Weiwei New Materials Co., Ltd. started in January 2025. We are located in the Bibiao Industrial Park in Yanshan County, Yunnan Province. We have two fully automatic production lines. We also have a professional R&D team. Our annual output of cryolite series products exceeds 10,000 tons. We can control the molecular ratio and purity of Potassium Hexafluoroaluminate precisely according to your needs.

Where This Product Is Used
High-End Grinding Wheels
Potassium Hexafluoroaluminate works as an active filler in resin and vitrified wheels. At grinding temperatures, it releases active fluorides. This lowers the friction coefficient at the grinding interface. It also reduces heat damage to the workpiece.
Special Fluxes and Brazing Materials
This product is an important active component in special fluxes. It removes oxide films from aluminum surfaces effectively. This promotes spreading and wetting of the solder.
Optical Glass and Specialty Ceramics
Potassium Hexafluoroaluminate serves as an additive. It improves optical properties and thermal stability.
Quality and Production Standards
We follow strict batch testing for Potassium Hexafluoroaluminate. Every batch goes through full testing for purity, fluorine content, and particle size. We hold an environmental impact report and a pollutant discharge permit. Our operations are fully compliant with local environmental laws.
We offer OEM and ODM services. You can customize product specifications and packaging. If you report any quality issues within 15 days of delivery, we will respond and resolve them.
Supply Capacity and Delivery
Our monthly production of cryolite series products is 2,000 tons. The minimum order quantity is 3 tons. In July 2025, we supplied 3,500 tons of electrolyte to Shandong Weiqiao Aluminum. From 2025 to 2026, we supplied over 2,000 tons of cryolite to Guizhou Xingren Aluminum. We support EXW, FOB, and DDP trade terms. Our transport resources are sufficient.
