Tungsten vs Carbon Fiber – What’s the Difference

Tungsten vs Carbon Fiber

Choosing the right material for a particular application significantly contributes to its performance and durability in manufacturing. Among the options available, the most popular are tungsten and carbon fibre industrial metals. However, choosing between the two can be challenging as they have many similarities in strength, stiffness, and thermal conductivity. In this blog, we will explore the differences between tungsten and carbon fibre industrial metals to help you make an informed decision.

What is Tungsten?

Tungsten is a rare metal that has been used for many industrial purposes. It is highly resistant to heat, corrosion, and high temperatures, which makes it ideal for engineering applications such as cutting tools, electrical contacts, and heating elements. The industry’s most common form of tungsten is wolfram, which has the highest melting point of all metals at 3695 degrees Celsius. Tungsten can also be alloyed with other metals for aerospace components due to its strength and density, making it an essential part of modern manufacturing processes.

What is Carbon Fiber?

Carbon fibre is a lightweight yet strong material made from thin strands of carbon. These strands can be woven into a cloth-like fabric lighter than steel but still as strong. It has become widely used in various industries due to its strength and durability, making it ideal for aerospace applications such as aircraft parts and rocket components. Carbon fibre can also be used for automotive components like body panels, high-end bicycles and vehicles, sporting goods equipment, medical implants and many other products.

Difference Between Tungsten and Carbon Fiber

The biggest difference between tungsten and carbon fibre is that tungsten is an extremely dense metal alloy. In contrast, carbon fibre is a lightweight composite material made from strands of carbon atoms. Tungsten has excellent heat resistance properties, making it great for applications requiring high temperatures. On the other hand, carbon fibre is incredibly light but still very strong and durable, making it perfect for aerospace or automotive applications.


Tungsten, also known as wolfram, is a chemical element known for its high density and strength, making it an ideal material for industrial applications. On the other hand, carbon fibre is a synthetic fibre composed of tightly bonded carbon atoms. It is light in weight but incredibly stronger than steel. This difference in composition gives each material its unique characteristics that suit particular applications.


Tungsten has an incredibly high melting point, which makes it a preferred choice for crucibles and other applications that require high heat resistance. It is also resistant to corrosion and radiation and is highly dense. Carbon fibre, on the other hand, is much lighter than tungsten, has high tensile strength and stiffness, and has excellent thermal conductivity. It is ideal for applications that require light but strong materials.


The cost of tungsten varies depending on its form and purity level. Materials such as tungsten carbide, an alloy of tungsten and carbon, are more expensive than pure tungsten. On the other hand, carbon fibre is relatively cheaper than tungsten but may become more expensive if custom formulations are required to meet specific application requirements.


Tungsten is extremely hard to machine, requiring specialized equipment and tools. Carbon fibre is easily machined, but it poses issues with delamination, making it difficult to machine it in thick sections. Therefore, tungsten is not ideal for mass production, while carbon fibre is.


Tungsten is often used in high-temperature applications such as rocket nozzles, electrodes, and heat sinks. It also produces X-ray targets, lighting filaments, and radiation shielding. Carbon fibre is ideal for applications requiring low weight and high strength, such as sports gear, aerospace, automotive parts, medical devices, and wind turbine blades.


Choosing between tungsten and carbon fibre depends on the application and the desired characteristics. While tungsten is stronger, denser, and heat resistant, carbon fibre is lighter, cheaper, and easily machinable. Therefore, when selecting between the two materials, manufacturers should consider the application requirements, cost, and ease of machining. We hope this blog has shed some light on the differences between the two industrial metals, helping you make an informed choice.
