Understanding the value of cast iron per kilogram is essential for manufacturers, recyclers, and buyers in the metal industry. Cast iron prices can fluctuate based on various factors including the material grade, market demand, and regional influences. This article delves into the different elements that affect the pricing of cast iron, offering insights to help you make informed decisions.
Key Takeaways
- Cast iron prices vary depending on material grades and standards, such as ASTM and DIN.
- The unit weight of casting significantly impacts the cost, with lighter castings generally being more expensive per kilogram.
- Market demand and supply play a crucial role in determining the price of cast iron.

Factors Influencing Cast Iron Prices
Material Grades and Standards
The price of cast iron is significantly influenced by the material grades and standards it adheres to. For instance, grey cast iron and ductile iron have different pricing structures based on their respective ASTM, DIN, and EN standards. Material grades requiring low tensile strength are generally cheaper compared to those requiring high tensile strength.
Unit Weight of Casting
The unit weight of the casting also plays a crucial role in determining its price. Castings weighing between 2 to 5 lb (1 to 2 kg) are priced differently compared to those weighing 50 to 100 lb (20 to 50 kg). It is difficult to estimate the price of casting with unit weight less than 1.0kg.
| Unit Weight of Casting | Price (USD/KG) |
|---|---|
| 1 – 2 kg | 1.41 |
| 2 – 20 kg | 1.30 |
| 20 – 50 kg | 1.30 |
| 50 – 1000 kg | 1.41 |
Market Demand and Supply
Market demand and supply dynamics are another critical factor. When the demand for cast iron is high and supply is limited, prices tend to rise. Conversely, an oversupply can lead to lower prices. To summarize, pig iron prices are affected by a variety of factors, including supply and demand, raw material costs, policy factors, and exchange rate factors.
Understanding these factors can help buyers and sellers make more informed decisions in the cast iron market.
Comparison of Grey Cast Iron and Ductile Iron Prices
Price Differences by Weight
When comparing the prices of grey cast iron and ductile iron, it’s essential to consider the weight of the casting. For instance, grey cast iron prices range from 1.30 to 1.41 USD/KG depending on the weight category. On the other hand, ductile iron prices range from 1.39 to 1.50 USD/KG. The price differences are influenced by the material grades and the tensile strength requirements.
| Weight Category (KG) | Grey Cast Iron (USD/KG) | Ductile Iron (USD/KG) |
|---|---|---|
| 1 – 2 | 1.41 | 1.50 |
| 2 – 20 | 1.30 | 1.39 |
| 20 – 50 | 1.30 | 1.39 |
| 50 – 1000 | 1.41 | 1.50 |
Applications and Uses
Grey cast iron is commonly used in applications where low tensile strength is sufficient, such as in meter module risers and various pipe fittings. Ductile iron, however, is preferred for applications requiring higher tensile strength, such as in automotive components and heavy machinery.
Tensile Strength Requirements
The tensile strength requirements significantly impact the pricing of cast iron. Grey cast iron typically has lower tensile strength, making it less expensive. In contrast, ductile iron, which requires higher tensile strength, is generally more costly. This difference is crucial for industries that need materials with specific mechanical properties.
Understanding the differences in pricing and applications between grey cast iron and ductile iron can help buyers make informed decisions based on their specific needs.
Regional Variations in Cast Iron Pricing
Price Trends in China
China is a significant player in the cast iron market, and its pricing trends often influence global rates. The geographical differences in cast iron prices are evident due to local considerations such as labor costs, environmental laws, and infrastructure development. For instance, the price for grey cast iron in China ranges from $1.30 to $1.41 per kg, depending on the unit weight and material grade.
Impact of Local Regulations
Local regulations can significantly impact cast iron pricing. Environmental laws, labor regulations, and import/export duties are some of the factors that can cause price fluctuations. Regions with stringent environmental laws may see higher prices due to the additional costs of compliance.
Global Market Influence
The global market also plays a crucial role in determining cast iron prices. Factors such as international trade policies, currency exchange rates, and global demand and supply dynamics can lead to price variations. For example, a surge in global demand can drive up prices, while an oversupply can lead to a decrease.
Understanding regional variations in cast iron pricing is essential for making informed purchasing decisions and negotiating better deals.
Additional Costs in Cast Iron Pricing
Machining and Painting
When considering the overall cost of cast iron, it’s important to account for additional expenses such as machining and painting. These processes can significantly increase the final price. Machining involves precise cutting and shaping, which requires specialized equipment and skilled labor. Painting, on the other hand, adds a protective layer to the cast iron, enhancing its durability and appearance.
Packing and Delivery
Packing and delivery are crucial components of the total cost. Proper packing ensures that the cast iron parts are protected during transit, reducing the risk of damage. Delivery costs can vary based on the distance and the weight of the shipment. It’s essential to factor in these costs to get a comprehensive understanding of the pricing.
Inspection and Certification
Inspection and certification are often required to meet industry standards and customer specifications. These processes involve thorough checks to ensure the quality and compliance of the cast iron products. While they add to the overall cost, they are indispensable for maintaining high standards and customer satisfaction.
