Structure Improvement (Grain Refining and Modification) Flux for Melting Recycled/Secondary Aluminum

• 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)
