Pure iron is a silvery-white metal that's easy to work and shape and it's just soft enough to cut through (with quite a bit of difficulty) using a knife. You can hammer iron into sheets and draw it into wires. Like most metals, iron conducts electricity and heat very well and it's very easy to magnetize. Cast iron is simply liquid iron that has been cast: poured into a mold and allowed to cool and harden to form a finished structural shape. The high carbon content of cast iron makes it extremely hard and brittle: large crystals of carbon embedded in cast iron prevents the crystals of iron to move. Wrought iron is a very different material made by mixing liquid iron . The result is an iron alloy with a much lower carbon content. Wrought iron is softer than cast iron and also much less prone to rusting.
