'<br>Iron can exist in many different types as per their composition, intended usage or percentage of iron in the material. There are basically three categories of iron with which we shall describe them and thereby give their respective uses in manufacturing and industrial activities. These are:<br><br><br>First, there is Pig Iron which is comparatively the cheapest of the three and is obtained from cast iron. It is brittle and does not have good thermal conductivity. Hence it is largely used in low temperatures and is known as cold-rolled steel. Due to its brittle nature, the strength and the toughness of this metal are less than that of other metals.

For example, a cast iron frying pan can break up into smaller particles if it comes in contact with too much heat.<br><br><br>Second, the second category is Ferric Iron which is also known as Carbon Steel. It is known for its high tensile strength, but it is also brittle and ductile. On the other hand, it has very low melting points. Due to its oxygen content, it is a good conductor of electricity and has very good thermal conductivity. On the downside, it is highly sensitive to fatigue and rusts easily.<br><br><br>Third, the fourth category is Wrought Iron, which is much better than the other two. Wrought Iron is made from pure carbon and is known for its excellent physical properties including high tensile strength and resistance to fatigue. On the downside, it is highly sensitive to fatigue and cannot be worked on low temperatures. On the positive side, it does not deteriorate with time unlike the other two metals mentioned above. Hence it is extensively used for applications in the aerospace and defense industry.<br><br><br>The fifth category of steel is Cast Iron and is made from pure carbon. While the other four metals mentioned above are already a mixture of carbon and iron-ore materials, cast iron is still a metal made entirely out of carbon. In addition to its physical properties, it is also known for its great tensile strength, ability to be molded into any shape imaginable and its high ability to resist corrosion. On the downside, casting requires skill and is quite expensive.<br><br><br>Many people think that Cast Iron is a material that is easily broken down and therefore needs to be worked harder. However, contrary to that notion, this alloy is extremely tough and is capable of withstanding extreme pressure. That is why it is often used to build ships. Furthermore, Cast Iron Alloys is very brittle but they have high tensile strength. This means that they can withstand tremendous amounts of force before the material breaks down.<br><br><br>There are several other types of metals that people often confuse with Cast Iron because they all contain some or all of these qualities. Examples of them include Steel, Tin, Aluminum, Brass and Copper. Steel and tin are considered to be the most brittle because they have less carbon content in them and therefore they are less likely to be formed into new compositions. The fourth type of iron alloys, which is the most popular is Copper. It is relatively hard, ductile, corrosion resistant and malleable and therefore it is frequently used in making steel and even other kinds of alloy steel.<br><br><br>In the same manner, Aluminum has very little carbon and is therefore much less likely to undergo alloying. The most popular types of these alloys are the ones made from either carbon steels or aluminum. When comparing the characteristics and properties of these materials it becomes apparent that they are very similar and it is only the differences that differentiate one from the other. The major difference lies in the fact that the carbon steels are much more brittle while aluminum is much less so. Also, when comparing these materials it is clear that the former is a much less malleable metal while the latter is a much harder metal.<br>'
