- Structure Improvement Flux are structure-control additives used during aluminum solidification to optimize α-Al grain structure and Si morphology (eutectic/primary), improving mechanical properties, castability, and overall product consistency.
Depending on alloy composition and Si level, the product family is categorized into Grain Refiners, Eutectic Si Modifiers, and Primary Si Refiners.
▶ Quick Information
Product Family: Structure Improvement Agents
Categories: Grain Refiner / Eutectic Si Modifier / Primary Si Refiner
Process: Aluminum melting & casting (pre-solidification structure control)
Benefits: Improved properties, uniform microstructure, reduced defects
Support: Product selection and application support based on alloy/casting conditions
▶ Detailed Information
The product range supports:
Grain refinement for α-Al grain uniformity
Eutectic Si modification for Si morphology control
Primary Si refinement for hypereutectic alloys to suppress excessive primary Si growth/agglomeration
Technical data sheets (TDS) and test reports are available upon request.Customized application conditions can be discussed based on furnace type, melt temperature, and feed material characteristics.For more detailed information on our products and manufacturing processes, please visit our website(https://www.dsliquid.com/en/products/fifth)
