The term cast iron, like the term steel, identifies a large family of ferrous alloys. Cast irons are multicomponent ferrous alloys. They contain major (iron, carbon, silicon), minor (<0.01%), and often alloying (>0.01%) elements.
Cast iron has higher carbon and silicon contents than steel. Because of the ...

Flake graphite iron finds use due to:
its cheapness and ease of machining;
low-melting temperature (1140-1200°C);
ability to take good casting impressions;
wear resistance;
high damping capacity;
a reasonable tensile strength of 108-340 MPa associated with a very high compressive strength, making it very suitable for applications ...
