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

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.

Types. There are four basic types of cast irons: white iron, gray iron, ductile iron, and malleable iron. White iron contains a large percentage of eutectic carbides which increase hardness at the expense of toughness. The presence of different carbides, produced by alloying, makes white iron extremely hard and abrasion resistant but very brittle.
