Gray Iron – Iron Casting Research Institute, Inc.

Sep 07, 1990  ABSTRACT: Gray iron is the most versatile of all foundry metals. The high carbon content is responsible for ease of melting and casting in the foundry and for ease of machining in subsequent manufacturing. The low degree or absence of shrinkage and high fluidity provide maximum freedom of design for the engineer.

Grey Cast Iron - an overview ScienceDirect Topics

Gray cast iron. Gray cast iron is a broad term used for a number of cast irons whose microstructure is characterized by the presence of flake graphite in the ferrous matrix. Such castings often contain 2.5%–4% carbon, 1%–3% silicon, and some additions of manganese ranging from 0.1% to 1.2%. This is one of the most widely used alloys of iron.

Gray iron is 2.5–4% carbon by weight, and additionally contains 1–3% silicon, which stabilizes the graphite. It has many of the attributes of basic cast iron, in that it is inexpensive and has a high flowability compared to steel when molten, but the graphite’s presence allows the iron to be somewhat less brittle, allowing easier machining.
