Tungsten: Unveiling the Steel-Like Strength Within


Tungsten, with its chemical symbol W, holds a prominent position in the periodic table with atomic number 74. Known for its remarkable strength and durability, tungsten has become a vital element in various industries. In this blog, we will explore the various facets of tungsten, from its properties and compounds to its applications and significance in modern technology.

Chemical Properties and Composition:

Tungsten boasts an atomic mass of approximately 183.84 atomic mass units (amu) and is situated in the sixth period of the periodic table. 

Electron configuration[Xe] 4f14 5d4 6s2             

or   1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 4f14 5s2 5p6 5d4 6s2, highlighting its transition metal nature. Tungsten typically exhibits a valency of +6, forming compounds like tungsten hexafluoride (WF₆) and tungsten trioxide (WO₃).

Physical Properties:

With a melting point of 3,422 degrees Celsius (6,192 degrees Fahrenheit), tungsten possesses the highest melting point of all elements. This extraordinary property, coupled with its density of 19.25 grams per cubic centimeter, makes tungsten a dense and resilient metal. Its hardness and high tensile strength make it comparable to steel, earning it the moniker "heavy metal."

Tungsten Compounds and Chemical Reactions:

Tungsten forms various compounds, including tungsten carbide (WC) and tungsten disulfide (WS₂). Tungsten carbide, a popular hard metal, is widely used in cutting tools and industrial applications due to its exceptional hardness and wear resistance. Tungsten disulfide, on the other hand, serves as a solid lubricant in extreme conditions.

Tungsten's chemical reactivity is relatively low, resisting corrosion and oxidation at elevated temperatures. However, it can react with fluorine and other strong oxidizing agents under specific conditions.

Occurrence and Production:

Tungsten is primarily found in minerals such as scheelite and wolframite. China, Russia, Canada, and Bolivia are among the leading producers of tungsten. The extraction process involves various methods, including gravity separation, flotation, and magnetic separation, depending on the ore's composition.

Applications and Uses:

The versatility of tungsten finds expression in a myriad of applications across industries. Some notable uses include:

1. Tungsten Carbide: Widely employed in cutting tools, mining equipment, and drill bits for its exceptional hardness.

2. TIG Tungsten: Used as an electrode in Tungsten Inert Gas (TIG) welding, providing a stable arc and high melting point.

3. Tungsten Foil: Applied in electronics and aerospace industries for its electrical conductivity and resistance to high temperatures.

4. Tungsten Grinders: Essential tools for sharpening tungsten electrodes in welding applications.

5. Tungsten Steel: Utilized in the production of high-speed steels and alloys for improved strength and durability.

6. Tungsten Crucibles: Crucial for melting and casting metals due to tungsten's high melting point.

7. C Welding Tungsten: A specialized tungsten electrode for welding carbon and stainless steels.

8. Tungsten Tubing: Employed in high-temperature applications, such as furnaces and aerospace components.

Tungsten Suppliers and Price Trends:

As a globally traded commodity, tungsten prices are influenced by factors like supply and demand, geopolitical events, and technological advancements. Reliable tungsten suppliers play a pivotal role in meeting the demands of industries requiring this robust metal.


Tungsten, the unyielding metal with a strength reminiscent of steel, stands as a testament to the remarkable properties found within the periodic table. From its diverse compounds to its crucial role in modern applications, tungsten continues to shape industries and technologies, showcasing its significance in the ever-evolving world of materials science and engineering.
