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.

Cast Iron Foundry, Gray Iron and Ductile Iron Casting

Gray Iron Casting. Gray iron is casted iron with a graphitic microstructure that typically has a chemical composition of 2.5 – 4% carbon and 1 – 3% silicon by weight. The graphite forms three-dimensional flakes within the metal, which appear as fine lines on the polished surface. These graphite flakes make gray iron more brittle than its counterparts.

Gray Iron – IspatGuru

May 08, 2014  Gray Iron. Gray iron (also called grey iron) is a type of cast iron that has a graphitic microstructure. It is named after the grey color of the fracture it forms, which is due to the presence of graphite. It is the most common cast iron and the most widely used cast material. Gray iron is one of the oldest cast ferrous products.

Machining Cast iron In a Lathe or Mill - STEAMSHED

Nov 28, 2019  Cast iron machining in a lathe or mill needs a very slow speed to cut it properly – too high and there will be sparks everywhere and your tools will need re-sharpening very quickly. As a general rule of thumb, to get a smoother finish on cast iron, you tend to need a finer tip on your cutting tool with very slow transition along the work.
