More ...DS Liquid’s aluminum flux is a metallurgical auxiliary material (additives) designed for the melting and refining of recycled aluminum and secondary aluminum.Degassing Flux (H₂ Gas Remover) is used to remove dissolved hydrogen gas from molten aluminum and other non-ferrous metals, helping to prevent pinhole defects and porosity formation in the final cast product.
DS Liquid’s Degassing Flux (H₂ Gas Remover) is a product range developed to effectively address hydrogen-related defects in secondary (recycled) aluminum and non-ferrous metal melting processes.During melting and holding, molten aluminum readily absorbs hydrogen due to moisture, scrap contamination, and surrounding process conditions.
Excess hydrogen can lead to pinhole defects and internal porosity in cast products, negatively affecting quality and mechanical properties.Degassing Flux is added to the molten metal to react with and release dissolved hydrogen, thereby reducing hydrogen content in the melt prior to casting.
This results in fewer internal defects, improved surface quality, and more stable mechanical performance of the final product.The product range includes Na-based and Non-Na-based formulations, available in powder and tablet forms, allowing flexible selection depending on process requirements.
Recommended operating temperatures typically range from 680°C to 730°C or above, depending on the specific grade.Degassing Flux is suitable for a wide range of aluminum processes including die casting, rolling, and extrusion, particularly at the melt treatment stage before casting.Technical data sheets (TDS) and test reports are available upon request.
Customized product selection and application conditions can be discussed based on furnace type, melt temperature, and alloy composition.For more detailed information on our products and manufacturing processes, please visit our website
