What Is Ductile Iron Casting & SG Iron Casting?
Understanding Ductile Iron (SG Iron)
Ductile Iron, also known as SG iron casting or spheroidal graphite iron, is a high-performance material characterised by its nodular graphite structure. This unique microstructure gives it excellent mechanical strength, toughness, and fatigue resistance, making it ideal for heavy-duty components that require long service life and reliability.
Why Choose SG Iron Casting?
-
Superior strength and ductility compared to traditional grey iron.
-
Excellent wear and impact resistance for demanding applications.
-
Cost-effective alternative to many steel castings with similar performance benefits.
-
Highly machinable and versatile for complex shapes and designs.
