Why Ductile Iron?

Ductile iron combines the versatility of steel with the casting ease of gray iron, offering an exceptional balance of strength, machinability, and cost-effectiveness. Its unique graphite nodules provide superior mechanical properties, including high tensile strength and excellent wear resistance, while maintaining better vibration damping and thermal conductivity compared to steel. Additionally, ductile iron’s ability to be cast into complex shapes with consistent quality makes it an ideal choice for a wide range of applications, from heavy machinery components to precision parts that require both durability and dimensional accuracy.

Green Sand Foundry

Farrar Corporation is proud to produce its ductile iron through the green sand casting process. This molding method utilizes recycled sand as the primary material, without any other additives besides clay and water. The moisture content within the mold itself provides the necessary binding structure for the sand.

The green sand casting approach allows Farrar to create high-quality ductile iron parts in an environmentally responsible manner. By repurposing recycled sand, Farrar minimizes waste and reduces the environmental impact of our manufacturing operations. Additionally, the lack of additional binding agents or chemicals further enhances the sustainable nature of this casting process.

Farrar’s commitment to green sand casting is a testament to our focus on delivering products that meet both stringent quality standards and environmental considerations. This production method enables the company to offer ductile iron components that are not only durable and fit-for-purpose but also aligned with the growing demand for sustainable manufacturing practices among its customers.
