Mineral information

Tungsten is a relatively inactive metal with excellent corrosion resistance and conductivity of electricity. It is a strong, thick, silver-grey metal with the highest tensile strength and the lowest thermal expansion of all metals. Its density is almost twice that of lead and comparable to gold.

It has the second highest melting point of all elements after carbon and the highest of all metallic elements – 3442^oC, the highest of all metallic elements.

Applications

Tungsten is a dense, high-melting-point metal that excels in extreme conditions, making it ideal for various high-temperature and high-performance applications. Some key applications include:

Furnace linings & high-temperature applications

• Tungsten is used in furnace linings, where its high melting point and thermal stability make it ideal for maintaining integrity in extreme temperatures.
• Common in industrial furnaces and kilns that operate at elevated heat levels, ensuring long-lasting performance.

Automotive & aerospace industries

• Tungsten alloys are used in automotive and aerospace components, such as turbine blades and exhaust systems, due to their strength and heat resistance.
• Provides durability and performance in engine components and aerospace structures exposed to high temperatures and mechanical stress.

Cutting & drilling tools

• Known for its hardness, tungsten is utilised in cutting tools, drills, and other wear-resistant components.
• Used in industries such as mining, construction, and metalworking for tools that need to withstand abrasive conditions.

Chemical processing & catalysis

• Tungsten is employed as a catalyst in chemical reactions due to its unique ability to support high reaction rates under extreme conditions.
• Found in applications such as hydrogenation, dehydrogenation, and other critical chemical processes.

Medical & radiation shielding

• Tungsten is used in medical apparatus, including radiation shielding for X-ray machines, CT scanners, and other diagnostic equipment.
• Its dense nature makes it highly effective in blocking harmful radiation, ensuring safety in medical environments.
