​​Advantages in Casting​

• Effective Deoxidation​​: Ferro silicon acts as a critical deoxidizer during molten metal processing. By reacting with oxygen, it minimizes oxide impurities, ensuring cleaner castings with fewer defects. This is vital for achieving uniform mechanical properties in components like engine blocks or machinery parts
• ​​Graphite Nodulization​​: In ductile iron production, ferro silicon promotes graphite spheroidization, replacing brittle carbides. This transformation enhances ductility and wear resistance, making it ideal for automotive and machinery applications
• ​​Carbon Content Control​​: Ferro silicon regulates carbon levels in cast iron, preventing carbide formation and improving fluidity. This reduces shrinkage porosity and ensures stable production yields
• ​​Alloying Flexibility​​: Different ferro silicon grades allow precise adjustment of silicon content. For example, FeSi75 is preferred for high-strength applications, while FeSi65 suits cost-sensitive projects requiring moderate performance

​​Application

• ​​Gray Cast Iron​​: FeSi65 and FeSi70 are widely used to refine graphite morphology, enhancing strength and thermal stability for components like pipes and manhole covers.
• ​​Ductile Iron​​: FeSi75 and FeSi72 facilitate nodulization, critical for producing high-performance gears and automotive parts.
• ​​Cast Steel​​: FeSi45 and FeSi65 serve as alloying agents in low-alloy steels, improving hardness and machinability for structural components.
• ​​Special Alloys​​: High-purity ferro silicon supports the production of heat-resistant alloys and magnesium metal via the Pidgeon process
