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 in Ductile Iron? (Composition)

If you were to do a chemical analysis of ductile iron, this is what you would normally find:
Iron ~94%
Carbon 3.2 – 3.60%
Silicon 2.2 – 2.8%
Manganese 0.1 – 0.2%
Magnesium 0.03 – 0.04%
Phosphorus 0.005 – 0.04%
Sulfur 0.005 – 0.02%
Copper <= 0.40%
To improve the strength of ductile iron, additional tin or copper can be added. To improve corrosion resistance, copper, nickel, or chromium can replace anywhere from 15-30% of the iron.
