Wrought Iron – Properties, Uses and Composition

Wrought Iron

Have you ever wondered what wrought iron is? This material has been used for centuries and is still a popular choice today. But what makes it so special? In this blog post, we’ll discuss wrought iron’s physical and mechanical properties, its composition, and how it can be used to create beautiful works of art.

Wrought Iron Physical Properties

Wrought iron is a low-carbon steel that is known for its malleability and strength. It has a low melting point, allowing it to be easily worked into various shapes. It also has excellent corrosion resistance due to its high chromium content. This makes it an ideal material for outdoor applications such as fencing and furniture.

Properties Metric Imperial
Density 7.7 g/cm3 0.278 lb/in3
Melting point 1540°C 2800°F

Wrought Iron Mechanical Properties

Wrought iron has excellent tensile strength and ductility, making it perfect for forging into ornamental shapes. It also has a high yield strength, so it can withstand heavy loads without breaking or deforming. This makes it an ideal material for structural applications such as bridges or buildings where high levels of support are needed.

Properties Metric Imperial
Tensile strength 234-372 MPa 34000-54000 psi
Yield strength 159-221 MPa 23000-32000 psi
Modulus of elasticity 193100 MPa 28000 ksi

Wrought Iron Composition

The composition of wrought iron varies depending on the production process. Still, it typically contains between 0.1%-0.2% carbon, 1%-2% manganese, 0%-0.5% silicon, 0%-0.04% sulphur, 0%-0.04% phosphorus, 2%-4% copper, 1%-3% chromium, 0%-1% nickel, 0%-4% molybdenum and up to 99% iron with trace elements of other metals like zinc and tin present in smaller amounts. These elements combine to make wrought iron one of the most durable materials available today.

Element Content (%)
Iron, Fe 99-99.8
Carbon, C 0.05-0.25
Phosphorus, P 0.05-0.2
Silicon, Si 0.02-0.2
Sulfur, S 0.02-0.1
Manganese, Mn 0.01-0.1

Wrought Iron Uses

Due to its unique combination of physical properties, wrought iron is often used in decorative applications such as fencing or furniture due to its strength and corrosion resistance as well as artistic projects due to its malleability when heated at high temperatures making it easy to shape into intricate designs using traditional blacksmithing techniques like hammering or twisting the metal while hot before cooling down again allowing them to hold their desired shape when cooled down again later on after they have been removed from the heat source.

Additionally, wrought iron can be used in structural projects such as bridges where its high tensile strength provides much needed support while also looking aesthetically pleasing due to its ornamental designs often used in these kinds of projects when the metal is visible from public viewings areas like walkways underneath them or roads running over them giving them an attractive appearance while also providing strong support structures that can last for many years with minimal maintenance required if protected properly from harsh weather conditions both natural & man made alike throughout their lifespan over time too helping keep any structures made out of this material looking great no matter how long they have been standing already.


Wrought iron is one of the most versatile materials known to man with a wide range of uses, including decorative artwork and structural supports alike, due to its unique combination of physical & mechanical properties all rolled up into one single package helping make this material truly stand out from all others around it in every way possible too! Its low melting point makes it easy to work with by heating up & shaping using traditional blacksmithing techniques, giving you limitless possibilities when creating your own custom designed items out this ancient yet timeless material today! With proper maintenance & protection against harsh weather conditions, both natural & man-made alike throughout their lifespan, helping keep any structures made out of this amazing material lasting forever no matter how old they may get! So why give wrought iron a try today? You won’t regret it!
