-
United Kingdom: Prices range from $1.80 to $2.20 per kilogram, influenced by currency exchange rates and import tariffs.
Asia:
-
China: Prices are lower, ranging from $1.50 to $1.80 per kilogram, due to lower labor and production costs .
-
India: Prices range from $1.60 to $1.90 per kilogram, influenced by domestic demand and export activities.
5. Comparison with Other Cast Irons
Ductile iron is often compared to other types of cast iron, such as gray iron and white iron, due to its unique properties and applications.
Price Comparison (Per Ton):
| Cast Iron Type | Price Range (USD) |
|---|---|
| Ductile Iron | $1,800 – $2,200 |
| Gray Iron | $1,500 – $1,800 |
| White Iron | $2,500 – $3,000 |
While ductile iron is generally more expensive than gray iron, it offers superior strength and ductility, making it suitable for more demanding applications.
6. Impact of Scrap Metal Prices
Scrap metal prices play a crucial role in determining the cost of ductile iron production. As of April 2025, scrap metal prices in the USA were reported at $0.65 per pound . Fluctuations in scrap metal prices can lead to corresponding changes in ductile iron prices, as foundries adjust their purchasing strategies to maintain profitability.
7. Forecasting Future Trends
The ductile iron market is expected to experience steady growth in the coming years. Factors such as increased infrastructure development, automotive manufacturing, and energy sector investments are anticipated to drive demand. However, challenges such as fluctuating raw material costs and environmental regulations may impact pricing stability.
