Cast iron is a type of ferrous metal that has more carbon than most other types. This gives it a high amount of strength. Although high in strength, it is quite brittle. The lack of other alloying elements outside of iron and carbon make it a relatively affordable ferrous metal. Webprocessing. Wrought iron has little carbon, enough to make it harder than pure iron, but still malleable. Cast iron has much more carbon which makes it much harder, but also brittle and not workable. Steel landed in between making it harder than wrought iron, but unlike cast iron, malleable and flexible. chelsea temple
