Argon is a colorless, odorless, and non-reactive inert gas widely used in various industries, particularly in metallurgy. In aluminum refining, argon plays a critical role as a carrier gas to inject flux powder into the molten mixture.
The method of flux injection using argon (or nitrogen) ensures even dispersion of flux, removes impurities, eliminates dissolved hydrogen, and improves the quality of the final aluminum product. Compared to manual application, this technique enhances efficiency, reduces metal loss, and lowers costs.
Thanks to its chemical inertness, argon prevents oxidation, minimizes the formation of alumina (Al₂O₃), and protects molten aluminum from defects such as gas porosity and inclusions. This makes it an optimal solution for producing high-quality aluminum and aluminum alloys.
