Pacific Alloy Casting Company manufactures cast iron parts using a range of iron alloys selected to meet structural, wear, and durability requirements across industrial applications. Iron castings offer versatility in performance, manufacturability, and cost-effectiveness, making them suitable for both general industrial use and severe service environments.
Ductile iron is a cast iron in which the graphite forms as spherical nodules rather than flakes. This graphite morphology reduces stress concentrations and allows the material to:
As a result, ductile iron bridges the performance gap between gray iron and steel.
Ductile iron is a cast iron in which the graphite forms as spherical nodules rather than flakes. This graphite morphology reduces stress concentrations and allows the material to:
A practical way to choose among our standard Ductile Iron Alloys is: A536 for standard ductile-iron parts, A439 when the environment is hot or corrosive, and A897A/ADI when you want much higher strength and hardness than conventional ductile iron can provide.
Pacific Alloy manufactures ductile iron components used in applications such as:
Final grade selection depends on mechanical requirements, service conditions, and design constraints.
In many applications, ductile iron has replaced steel castings due to its favorable balance of performance and cost. A well-known example is the widespread use of ductile iron crankshafts in automotive engines, where ductile iron provides:
Similar material trade-offs are common in industrial equipment and machinery components.
If you’re evaluating iron castings for a specific application and need guidance on material selection or production capability, Pacific Alloy’s team is available to help.
