What is the difference between iron and wrought iron?

Iron and wrought iron are related materials, but they have distinct differences in terms of composition, properties, and uses.

Iron:

Composition: "Iron" typically refers to the chemical element iron (Fe) in its pure form. Pure iron is relatively soft and ductile.

Properties: Pure iron is malleable and has a silver-gray appearance. It has a relatively low melting point and can be easily shaped and welded.

Uses: Pure iron is not commonly used in industrial applications because of its softness and low strength. It is mainly used as a base material for the production of various alloys, such as steel.

Wrought Iron:

Composition: Wrought iron is an iron alloy that contains a small amount of carbon (usually less than 0.1%), along with other impurities like phosphorus and sulfur.

Properties: Wrought iron is known for its toughness, corrosion resistance, and malleability. It has a fibrous structure due to the presence of slag inclusions, giving it a distinctive grain pattern. Wrought iron is tough and can withstand heavy loads without shattering.

Uses: Wrought iron has a long history of use in blacksmithing and forging. It was traditionally used to create decorative elements, gates, railings, and ornamental objects. 

In summary, the key difference between iron and wrought iron lies in their composition and properties. Iron, in its pure form, is a basic element and is relatively soft and unsuitable for most industrial applications. Wrought iron, on the other hand, is an alloy of iron with a small amount of carbon and other impurities. It is known for its strength, toughness, and distinctive grain pattern and has been historically used in blacksmithing and decorative ironwork.
