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.

Gray Iron Castings Manufacturer Gray Iron

Oct 06, 2017  Gray Iron Castings Microstructure. Gray iron derives its properties from flake graphite in its microstructure. Its unique attributes include excellent machinability. When the composition of the molten iron and its cooling rate are suitable, the carbon in the iron separates during solidification and forms interconnected graphite flakes.

Gray Iron Castings Foundry and Supplier -

Grey iron – Flake graphite provides gray iron with unique properties (such as excellent machinability) at hardness levels that produce superior wear-resistant characteristics, the ability to resist galling and excellent vibration damping. Grey iron is sometimes spelled gray iron. Strength and hardness are sensitive to section thickness in gray iron castings.

Understanding cast iron and repairing damaged castings ...

Cast iron differs from other ferrous metals mostly by the extra carbon that is found in flake or spherical form. The presence of the extra carbon interrupts the continuously linked structure of iron molecules.

Cast Irons Selection Guide: Types, Features, Applications ...

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.
