What is SG Casting? Unveiling the Strength and Reliability of Spheroidal Graphite Iron

SG Casting, also known as Spheroidal Graphite Iron Casting or Ductile Iron Casting, is a specialized casting process that delivers exceptional strength, flexibility, and durability. By adding magnesium to molten iron, the graphite inside forms into smooth nodules rather than brittle flakes, drastically improving the metal’s mechanical properties. The result is a material that offers the toughness of steel with the wear resistance of cast iron.

This combination of qualities makes SG Casting a preferred choice for automotive components, heavy machinery parts, construction fittings, water pipelines, and agricultural equipment. It is capable of withstanding high loads, absorbing vibrations, and resisting corrosion, all while remaining cost-efficient and adaptable to complex designs.

At Sagar Foundry, we produce SG Castings using advanced melting, molding, and inspection technologies to ensure every piece meets exact specifications and delivers consistent, long-lasting performance in demanding industrial applications.
