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.

WebJul 2, 2024 · It makes the cast iron hard and brittle. Since too much sulfur gives unsound castings, therefore, it should be kept well below 0.1% for most foundry purposes. #3 Manganese. Manganese makes the cast iron white and hard. It is often kept below 0.75%. This helps to control influence over the harmful effect of sulfur.

WebBecause it is brittle, cast iron is almost certain to shatter if dropped. Since it is cast in a mold, certain forms are more suitable to cast iron than to wrought iron.
