Iron is the transition metal which is most widely used because it is relatively abundant in nature and processed easily. Pure iron is not so strong, but when mixed with other metals and carbon which is obtained very hard steel. Iron ore usually contains hematite (Fe2O3) stained by sand (SiO2) about 10%, as well as little sulfur, phosphorus, aluminum and manganese compounds.
Iron is the metal that most commonly used among all of metals, which encompasses as many as 95 percent of all metal tires produced worldwide. The combination of cheap price with its power make it very necessary, especially in use such as trains, shipbuilding boats, and structural components for buildings. Iron waja is the most recognizable iron alloy, and part of the form formed by iron includes:
☆ Raw iron or Pig iron containing 4% – 5% carbon with some bendasing such as sulfur, silicon and phosphorus. The interest of it, it’s a mediation of iron ore to cast iron and iron.
☆ Cast iron contains 2% – 3.5% carbon and small quantities of manganese. Bendasing contained in raw iron which may give a bad impression on the properties of materials, such as sulfur and phosphorus, has been subtracted to the acceptable stage. It has a melting point in the 1420-1470 K range, which is lower than the two major components, and it makes the first fused product when carbon and iron are heated simultaneously. The mechanical properties vary, depending on the form of carbon that absorbed into the alloy. Cast iron ‘white’ contains carbon in the form of cementite, or iron carbide.
☆ Carbon iron contains between 0.5% and 1.5% carbon, with small amounts of manganese, sulfur, phosphorus, and silicon.
☆ Wrought iron contains less than 0.5% carbon. It is hard, easy to bend, and not easily dilated against the raw iron. It has a small amount of carbon, some tenths of a percent. If sharpened to be thin, it quickly loses his sharpness.
☆ Alloy steel contains an alternating carbon content as well as other metals, such as chromium, vanadium, molybdenum, nickel, tungsten and so on.
☆ Iron oxide (III) is used in the income of magnetic stances in the computer. It is often mixed with other ingredients, and perpetuates their characteristics in solution.
The Usage of iron is very important, because the material is strong and durable. So that, we have initiative to make iron furniture and make creation to another kind of uniquely form.
