Customized Gray and Ductile Iron Casting Parts for Investment in Quality Casting Services

In the world of industrial manufacturing, customized gray and ductile iron casting parts represent fundamental components across numerous sectors. Our investment in quality casting services ensures that every iron casting delivers optimal performance, durability, and value for demanding applications from automotive to heavy machinery.

Premium Iron Material Specifications

Our foundry specializes in both gray iron and ductile iron formulations, each selected for specific performance characteristics:

Gray Iron Castings (Grades G2500-G4000) leverage the natural graphite flake structure that provides exceptional vibration damping capacity - approximately 20-25 times greater than steel . This material delivers tensile strength from 25,000 to 40,000 psi and compression strength approximately four times higher, making it ideal for applications requiring excellent wear resistance and stability . The graphite flakes also provide natural lubricity, reducing friction in moving assemblies.

Ductile Iron Castings (Grades 60-40-18 to 120-90-02) feature a nodular graphite structure created through magnesium treatment, delivering superior mechanical properties with tensile strength reaching 120,000 psi and elongation up to 18% . The spherical graphite nodules provide enhanced impact resistance and fatigue strength, with toughness comparable to many steel grades while maintaining excellent castability and machinability .
