Refining Flux is a high-performance auxiliary material specially designed for the refining treatment of aluminum and its alloys (excluding high magnesium content alloys). As a crucial product in the aluminum smelting process, it is available in three practical forms: powder, granule, and tablet, which can meet the diverse operational needs of different smelting scenarios. The product presents a clean white powder appearance, ensuring easy identification and application. It is packaged in two specifications: 2kg/bag and 20kg/carton, which is convenient for storage, transportation, and quantitative use in production. To maintain its performance, the Refining Flux must be stored in a dry and ventilated environment, and its validity period is 1 year from the date of production. This aluminum refining flux is committed to improving the quality of aluminum alloy castings, reducing production costs, and optimizing the smelting process, making it an indispensable choice for aluminum processing enterprises.

The most prominent advantage of this Refining Flux is its remarkable ability to reduce non-metallic impurities and cavities in castings. In the aluminum smelting process, non-metallic impurities and internal cavities are the main factors affecting the mechanical properties and service life of castings. By adding this flux, these defects can be significantly reduced, thereby improving the overall quality and qualification rate of aluminum alloy products.
It enables easy separation of slag from molten aluminum. The slag generated during smelting often adheres to the surface of the molten aluminum or mixes with it, which is difficult to remove. This flux can change the properties of the slag, making it easy to separate from the molten aluminum, simplifying the slag removal process, and saving labor and time costs.
The product effectively reduces metal smelting loss. The separated slag does not agglomerate, and the metal content in the slag is extremely low. This means that less aluminum metal is lost with the slag, maximizing the utilization rate of raw materials and reducing the production cost of enterprises.
During the entire application process, no toxic gases or obvious smoke are emitted. This feature not only protects the health of workers but also prevents corrosion and damage to production equipment. At the same time, it meets the requirements of environmental protection regulations, helping enterprises achieve green production.
The Refining Flux is easy to use. It does not require complex operation procedures or special equipment. It can be directly added to the molten aluminum according to the specified proportion, which is suitable for various smelting scales from small batch production to large-scale industrial production.
