Pure iron is a brittle and hard material that is classified as a metal in the eighth group of the Periodic Table of the Elements and is the fourth most abundant element in the earth’s crust. It is estimated that most of the Earth’s core (five percent) and iron makes up about 95 percent of all metals produced worldwide. Because of this, it is known as the most commonly used metal.

What is scrap iron?
Early humans produced iron purely from iron ore; However, it is not yet known from what date early humans began making and using this metal from ore. According to research, in the past the weapons used by commanders and rulers were made of iron, and they even found that the silk king belt was made of this material. At the same time, metallic iron was ceremonial and very expensive, and its manufacture was small but very expensive. During the Parthian period, the production of this metal material declined so much that it was only imported via China.
Transformation means the same as phase change with temperature change. The best example of a metal transformation is its transformation. This product is available in three forms: Beta, Gamma, and Delta. As the molten iron gradually cools, it turns into delta iron around 1538. Its lattice constant is 2.93 angstroms, it has paramagnetic properties, and its crystal structure is in the shape of a center-filled cube or BCC. If cooling continues, at a temperature of 1394 the existing crystal structure changes to a full face cube, or FCC. This type of formed iron is called stanite or gamma.
This phase reaches a steady state at a temperature of 1394 to 912. At 912 degrees Celsius, another transformation of this metal, alpha iron, called ferrite, is formed. This allotrope is stable from 912 to -273 ° C and has a structure similar to delta iron. Iron has many uses in different areas. Due to its high strength and resistance to the size of metals, as well as its cheapness, it is used in industrial machinery, transportation equipment, in the construction of structures, hulls of large ships, and in the manufacture of automobiles. It should be noted that the types of iron beams (mentioned above) and rebar are the most commonly used in construction. You can find more information about scrap iron prices our website.
