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 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.

Cast Iron vs Cast Steel Metal Casting Blog

Aug 04, 2021  Cast iron is often cheaper than cast steel because of the lower material costs, energy, and labor required to produce a final product. Raw steel is costlier to purchase, and it requires more time and attention to cast. When designing cast products, however, it is worth considering long-term use and replacement costs.
