The Applications of Different Types of Cast & Ductile Iron

As a 55-year old cast iron foundry in Kolkata, we have researched and studied the glorious history of iron thoroughly. The transformation of iron from 3,000 years ago to today is revolutionary and the processes are beyond commendable. Centuries have been spent by the blacksmiths until the invention of the cast iron in the industrial age.

Ever since then, cast iron and ductile iron have evolved its new form while progressing in the terms of its composition, microstructure, and mechanical properties. While there are multiple applications for the modern-day iron made in the cast iron foundries, some of them are listed below:

Grey Iron Applications

Grey cast iron is a type of iron found in castings known for its grey color and appearance caused by graphite fractures in the material. It is mainly used to make cylinder heads, gas burners, enclosures, and housings because of the key characteristics of gray iron and its ability to resist wear and tear, especially when lubrication supply is limited.

Ductile Iron Applications

Owing to its multiple benefits, ductile iron is used to make heavy-duty gears, automotive and truck suspension components, hydraulic components, and automobile door hinges. The fact that ductile iron can be broken down into different grades, yields strength, and is wear-resistant, makes ductile iron, the prime choice. Its ductility makes it another great choice for great designs.

White Iron Applications

Mainly used for mixer paddles, liner plates for ball mills, augers and dies, coal chutes, and wire guides for drawing wires, White Iron is wear and abrasion-resistant. The process that is used to make white iron results in a brittle material that is very resistant to wear and abrasions.

Malleable Iron Applications

Through an annealing heat treatment, the brittle structure as the first cast is transformed into the malleable form. Malleable Iron is the iron that has the ability to retain and store lubricants, the non-abrasive wear particles, and the porous surface which traps other abrasive debris. Malleable iron is used for heavy-duty bearing surfaces, chains, sprockets, connecting rods, drive train and axle components, railroad rolling stock, and farm and construction machinery.

Compacted Graphite Iron Applications

As the name suggests, compacted graphite iron is famously used in commercial applications. Similar to ductile iron, compacted graphite iron is produced by adding magnesium to a desulfurized base iron. The combination of both the properties of creates a higher strength and thermal conductivity product.

Choosing Between Ductile Iron And Traditional Cast Iron

Each casting foundry of India is known either for their Ductile Iron or the Traditional Cast Iron or both. While both the types are cast in the same foundry, their properties and varied and how. From applications to different resistance-levels, both the iron types play a pivotal role in the construction industry.Choosing a suitable kind for a particular job is extremely important and knowing the basics, tend to help. Below is a list of few basic differences between Ductile Iron and Traditional Cast Iron.
