What is Ductile Iron Used For? (Applications)

Ductile iron is great for use where you need strong metal with wear resistance.

Here is a sample list of things made from or contain ductile iron:

Pipe and pipe fittings (almost 50% of ductile iron sold in the US is for pipe and fittings)

Axles

Connecting rods (like in engines)

Crankshafts

Cylinders

Disc brake calipers

Gears and Gear Boxes

Housings and manifolds

Hydrostatic Barrels

Idler arms

Large Machines

Machine Tooling

Military uses

Piano Harps (the part that holds the strings of a piano)

Spindle supports

Steering knuckles

Suspension system parts

Truck axles

Valves (especially high-pressure valves)

Wheel hubs

Yokes for power transmission

What is the difference between Ductile Iron and Cast Iron?

Cast iron refers to all iron parts that are cast and have a high carbon content, but in normal usage,“cast iron”refers to gray iron, the cast parts with weaker iron structures containing graphite flakes. Ductile iron must specifically have the spherical graphite structure in the metal.

Regular cast iron can be cast cheaply, machined very easily, and strength can be added through heat treating. Gray iron lacks the strength and durability of ductile cast iron. Ductile iron castings are not much more expensive than gray iron castings yet if there is no need for the benefits of ductile iron you should probably stick with the gray iron castings.
