How does cast iron differ from pure iron

Ductile iron is produced by adding a trace amount of magnesium, which causes the formation of spheroidal graphite in the alloy. White cast iron has white colored cracks when broken. That is due to the presence of iron carbide impurities. Likewise, the presence of some other compounds can provide desired properties to the cast iron. Cast Iron: Cast iron is a hard, relatively brittle alloy of iron and carbon which can be readily cast in a mold.

Iron: Pure iron is not composed of carbon, but iron alloys can have different percentages of carbon. Cast Iron: Cast iron has relatively a low melting point. Iron: Rust formation occurs on the surface of iron and iron alloys except stainless steel. Cast Iron: Cast iron undergo rust formation. Iron: Iron and most iron alloys are malleable. Cast Iron: Cast iron is less malleable and is brittle except malleable cast iron.

Iron is a metal. It is used in the production of different types of metal alloys which are used for different purposes depending on their favorable properties. Cast iron is one such form of iron. Cast iron is usually brittle with the exception of malleable cast irons. Cast irons are now popular engineering materials with a wide range of applications because of their low melting point, good machinability, resistance to wear and deformation, and good fluidity.

Cast iron is also resistant to oxidation effects of rusting. Iron is a pure metal, existing as a single element whereas cast iron is alloyed iron which is iron alloyed with elements such as carbon or silicon. Iron metal undergoes oxidation when exposed to air and moisture to form rust while cast iron is not oxidized by moisture.

Iron metal has consistent properties while those of cast iron vary depending on the type of alloying element added. Cite APA 7 ,. Difference Between Iron and Cast Iron.

After heating the iron, a metalworking company will bend or work it using a hammer. Aside from their nuances in composition, there are other differences between cast iron and wrought iron. As previously mentioned, they are produced in different ways. Cast iron is made through casting, whereas wrought iron is made by heating and bending or working iron multiple times.

As a result, most metalworking companies will agree that cast iron is easier to produce than its wrought iron counterpart. Wrought iron is also stronger than cast iron. Each time wrought iron is heated and worked, it becomes a little stronger. Because of its strength, wrought iron is often used in commercial applications.
