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.).
