Tungsten Carbide Facts
Tungsten Carbide Properties
Tungsten carbide is a chemical compound consisting of tungsten and carbon, and it has a number of unique properties that make it useful in a variety of applications. Some of the most important properties of tungsten carbide include:
High hardness: Tungsten carbide is one of the hardest known materials, with a hardness rating that is typically between 8.5 and 9.5 on the Mohs scale. This makes it ideal for use in applications where resistance to scratching and wear is important, such as in cutting tools and abrasives.
High melting point: The melting point of tungsten carbide is typically between 2900 and 3200 degrees Celsius, which is significantly higher than the melting point of pure tungsten. This makes tungsten carbide useful in applications where resistance to high temperatures is important, such as in the production of cutting tools and high-strength alloys.
High density: The density of tungsten carbide is typically between 14.5 and 15.5 grams per cubic centimeter, which is significantly higher than the density of pure tungsten. This means that tungsten carbide is heavier and stronger than pure tungsten, which is useful in applications where weight and strength are important.
Non-magnetic: Tungsten carbide is not magnetic, which makes it useful in applications where a non-magnetic material is required, such as in the production of electrical contacts and magnetic field sensors.
Good thermal conductivity: Tungsten carbide has good thermal conductivity, which means it can transfer heat effectively. This property is useful in applications where heat management is important, such as in the production of heat sinks and other cooling devices.
What is Tungsten Carbide Used For?
Tungsten carbide is a versatile material with a number of important industrial and commercial applications. Some of the most common uses for tungsten carbide include:
Cutting tools: Tungsten carbide is widely used in the production of cutting tools for metalworking, woodworking, and other applications. Because of its high hardness and resistance to wear, tungsten carbide can be used to make tools that can cut through materials that are difficult to machine, such as hardened steel or titanium alloys.
Abrasives: Tungsten carbide is also used in the production of abrasive materials, such as grinding wheels and sandpaper. Because of its hardness and durability, tungsten carbide particles can be used to effectively remove material from a variety of surfaces without wearing down quickly.
High-strength alloys: Tungsten carbide is sometimes used as a reinforcement material in high-strength alloys. When mixed with other metals, such as cobalt or nickel, tungsten carbide can improve the strength and toughness of the alloy, making it more resistant to impact and wear.
Wear-resistant coatings: Tungsten carbide is often used as a coating material to improve the wear resistance of other materials. For example, tungsten carbide coatings can be applied to metal surfaces to protect them from abrasion and erosion.

Tungsten Carbide vs Tungsten
Tungsten carbide and tungsten are similar in many ways, but there are some important differences to consider. Tungsten is a chemical element with the atomic number 74 and the symbol W. It is a hard, dense, silvery-white metal with a high melting point and a number of important industrial applications.
Tungsten carbide, on the other hand, is a chemical compound consisting of tungsten and carbon. It is even harder and more durable than pure tungsten, and has a higher melting point. Tungsten carbide is commonly used in the production of cutting tools, abrasives, and high-strength alloys, and is also sometimes used in the manufacture of jewelry and other items.
One of the key differences between tungsten and tungsten carbide is their hardness and durability. Tungsten carbide is much harder than tungsten, which makes it more resistant to scratching and other forms of damage. Tungsten carbide is also more resistant to tarnishing and corrosion, which means it maintains its appearance over time. However, tungsten is generally less expensive than tungsten carbide, which may make it a more affordable option in some applications.
Tungsten Carbide Hardness
Tungsten carbide is a very hard material, with a hardness rating that is typically between 8.5 and 9.5 on the Mohs scale. This makes it one of the hardest materials known, surpassed only by a few other substances such as diamond and cubic boron nitride. The high hardness of tungsten carbide makes it ideal for use in applications where resistance to scratching and wear is important, such as in cutting tools, abrasives, and high-strength alloys.
Tungsten Carbide Density
The density of tungsten carbide varies depending on the exact composition of the material, but it is generally between 14.5 and 15.5 grams per cubic centimeter. This is significantly higher than the density of pure tungsten, which is 19.25 grams per cubic centimeter, and it is also higher than the density of most other metals. The high density of tungsten carbide is one of the reasons why it is often used in applications where weight and strength are important, such as in the production of armor-piercing rounds and high-strength alloys.
Tungsten Carbide Melting Point
The melting point of tungsten carbide is between 2900 and 3200 degrees Celsius, depending on the exact composition of the material. This is significantly higher than the melting point of pure tungsten, which is 3422 degrees Celsius, and it is also higher than the melting point of most other metals. The high melting point of tungsten carbide makes it useful in applications where resistance to high temperatures is important, such as in the production of cutting tools and high-strength alloys.
How Strong is Tungsten Carbide
Tungsten carbide is a very strong material, with a high resistance to scratching and other forms of wear. In terms of its mechanical properties, tungsten carbide is typically rated as having a hardness of between 8.5 and 9.5 on the Mohs scale, which is one of the hardest known materials. It also has a high melting point, typically between 2900 and 3200 degrees Celsius, and a high density, typically between 14.5 and 15.5 grams per cubic centimeter. These properties make tungsten carbide ideal for use in applications where strength and durability are important, such as in cutting tools, abrasives, and high-strength alloys.
Tungsten Carbide vs Titanium
Tungsten carbide and titanium are both strong, durable materials with a number of important industrial applications. However, there are also some significant differences between these two materials that make them suitable for different types of applications.
One of the key differences between tungsten carbide and titanium is their hardness. Tungsten carbide is much harder than titanium, with a hardness rating that is typically between 8.5 and 9.5 on the Mohs scale. This makes it ideal for use in applications where resistance to scratching and wear is important, such as in cutting tools and abrasives.
Titanium, on the other hand, is much less hard than tungsten carbide, with a hardness rating of around 6 on the Mohs scale. This makes it less suitable for use in applications where extreme hardness is required, but it also means that it is more ductile and can be formed into complex shapes more easily than tungsten carbide.
Another difference between these two materials is their density. Tungsten carbide is significantly denser than titanium, with a density of between 14.5 and 15.5 grams per cubic centimeter. This means that tungsten carbide is heavier and stronger than titanium, which is useful in applications where weight and strength are important. However, it also means that tungsten carbide is less porous and less biocompatible than titanium, which can be a disadvantage in some applications.
Overall, tungsten carbide and titanium are both valuable materials with unique properties that make them suitable for different types of applications. Which material is best for a given application will depend on the specific requirements and objectives of the project.
Is Tungsten Carbide Magnetic
Tungsten carbide is not magnetic. This is because tungsten carbide is made up of a mixture of tungsten and carbon atoms, and neither of these elements are magnetic. In fact, tungsten carbide is often used in applications where a non-magnetic material is required, such as in the production of electrical contacts and magnetic field sensors.
It is important to note that some tungsten carbide alloys may contain small amounts of magnetic materials such as cobalt or nickel. However, the amount of these materials is typically very small, and the overall magnetic properties of the alloy will be determined by the dominant non-magnetic elements. In general, tungsten carbide alloys can be considered to be non-magnetic.
