Specific weight of iron, properties, applications and values table

Iron is an element of the eighth group of the secondary subgroup of the corresponding table of elements and is one of the most common metals in the Earth’s crust, ranking second after aluminum. Iron in its simple form is a malleable white metal with a silvery shade. This type of material has a high ability to undergo chemical reactions, especially corrosion in air at high humidity and temperature. In pure oxygen, iron in its simple form burns. In a finely dispersed state, it can ignite spontaneously in air.

Usually, the name iron refers to its various alloys with an impurity content of up to 0.8 percent. These impurities make it possible to improve the ductility and softness of the pure metal. Carbon alloys are used: steels with a carbon content of up to 2.14 percent and cast irons with a carbon content of more than 2.14 percent, as well as alloys with the addition of alloying metals. In its pure form, iron is very rarely found in nature, more often in iron-type nickel meteorites. In terms of abundance in the world, it ranks fourth.

Table of the specific weight of iron

Since iron is a complex material, it is not possible to calculate the weight of iron, namely its specific weight, independently in field conditions. These calculations are carried out in specialized chemical laboratories. However, the average specific weight of iron is known and is 7.874 g/cm3.

To simplify calculations, below is a table with the values of the specific weight of iron, as well as its weight depending on the units of calculation.

Properties of iron

Iron is a typical white metal with a silvery and grayish shade. It has good ductility, pronounced magnetic properties, and also changes its properties well under the influence of impurities. Magnetism is characteristic of iron.

This type of element is divided into four modifications according to its crystal structure:

• Alpha iron. This type of iron has ferromagnetic properties with a body-centered cubic lattice structure. Iron remains in this state up to 769 degrees Celsius.
• Beta iron. This type of iron differs from the previous one only in magnetic properties and lattice parameters. Iron acquires this state in the range from 769 to 917 degrees Celsius.
• Gamma iron. The difference of this type lies in the structure of the lattice: it changes from a body-centered state to a face-centered one. This type is characteristic of temperatures from 917 to 1394 degrees Celsius.
• Delta iron. It differs only in lattice parameters and forms above 1394 degrees Celsius.

Approximately about 95 percent of all metallurgical production is accounted for by iron, which makes it one of the most in-demand metals in the world. The main areas include:

• Using iron as the main component of cast irons and steel
• Using it in alloys based on other components
• Using iron oxide to manufacture long-term computer memory devices
• Iron powder is used as toner in black-and-white laser printers
• Application in the production of electric motors and transformers
• Use in the etching process for printed circuit boards
