Cast Iron

An alloy of carbon and iron containing over 1.7 percent carbon. However, carbon contents exceeding about six percent are too weak and brittle to be of much use. Cast iron has a low tensile strength and is quite brittle, but can be cheaply produced in intricate shapes. It was widely used in making such things as mowing machine frames, heavy lugged wheels, and large gears with teeth not subjected to high stress. Because of its brittleness and hardness, little machining was done on cast iron parts.
