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.

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.
