What is Grey Cast Iron?

 

Grey cast iron (a.k.a. gray iron) is a type of iron found in castings known for its grey color and appearance caused by graphite fractures in the material. Specifically, what makes grey iron “grey iron,” is the graphite flake structure that is created during the cooling process from the carbon that is in the component.

Grey iron is a result of both the materials used and the process used to cast a part. In other words, the properties of the grey iron will change depending on what materials are melted together to pour into the mold as well as the process that is used for casting (it is primarily the cooling part of the process that defines the characteristics of the cast part versus other parts of the process.).

 

Grey Iron Magnified to Show the Flakes of Graphite

 

 

 

There are more pounds of grey iron castings produced every year throughout the world than any other type of casting. Just about every manhole cover is from grey iron and the disc brakes on your car are most likely grey iron as well. Other common uses for grey iron include:

  • Gears
  • Hydraulic components
  • Automotive suspension components
  • Plow shares
  • Pumps
  • Linkages
  • Stove parts
  • Steering knuckles
  • Tractor parts
  • Valves
  • Truck suspension components
  • Other truck parts
  • Wind turbine housings.
  • Weights and counter-weights
  • Machinery bases
