Cast iron is a ferrous alloy which has more than 2% carbon in it. Though it can have any percentage of carbon between 2% to 6.67%, but practically it is in between 2% to 4% only. It has got its name due to its excellent casting qualities. It is hard and brittle. There
Piston Ring Handbook
At Federal-Mogul grey iron piston rings are cast as individual rings in a noncircular shape; there are other ring manufacturers who cut the individual rings from pots or cuffs. The rings are generally machined to the required shape by means of double cam turning , a process in which the ring blank, already axial ly ground, is copy turned simultaneously on the inside and outside diameters.
