What are the components of wrought iron?

Views: 340 Update date: Mar 16,2023
Wrought iron is a type of iron alloy that has been in use for centuries. It was widely used in the construction of buildings, bridges, and other infrastructure before the advent of steel. Wrought iron is known for its high durability, malleability, and ductility, making it an ideal material for various applications. 

Wrought iron is primarily made up of iron and a small amount of carbon. However, the manufacturing process involves several steps, which also introduce other elements into the alloy. Here are the components of wrought iron:

Iron: 

Wrought iron is primarily made up of iron, which makes up about 99% of the alloy. Iron is the most important component of wrought iron and gives it its strength and durability.


Carbon: 

Wrought iron contains a small amount of carbon, typically less than 0.1%. Carbon is added to iron to improve its strength and hardness. However, the carbon content in wrought iron is much lower than in steel.

Slag: 

During the manufacturing process, impurities in the iron are removed by adding a flux, which reacts with the impurities to form slag. Slag is a byproduct of the manufacturing process and is essentially a mixture of oxides, silicates, and other compounds. Slag gives wrought iron its distinctive grainy texture and appearance.


Silicon: 

Silicon is another element that is introduced into wrought iron during the manufacturing process. It is added to improve the quality of the iron by removing impurities and improving its malleability and ductility.


Manganese: 

Manganese is another element that can be found in wrought iron. It is added to improve the strength and toughness of the alloy.


Phosphorus: 

Phosphorus is sometimes present in small amounts in wrought iron. It is a non-metallic element that can improve the hardness and strength of the alloy.
