Gray Iron Casting:

Gray iron, also known as grey iron, is a type of cast iron that is named for its characteristic gray color when fractured. It is widely used in casting applications due to its excellent castability, thermal conductivity, and damping capacity. Gray iron is relatively easy to cast and is known for its ability to produce intricate and detailed parts. It is often used for applications where strength and wear resistance are not the primary requirements, such as engine blocks, pipes, and decorative items.

Ductile Iron Casting:

Ductile iron, also called nodular cast iron or spheroidal graphite iron, is a type of cast iron that has been specially treated with trace elements to change the nature of the graphite within the material. This modification results in a more flexible and ductile structure, making ductile iron stronger and more impact-resistant than gray iron. Ductile iron retains the casting advantages of gray iron while also offering improved mechanical properties, making it suitable for applications where strength and toughness are essential. It is commonly used for components like crankshafts, gears, and heavy machinery parts.
