About Tungsten (W)

Pure tungsten is a hard, lustrous and silvery‐white metal. It possesses the highest melting point among all elements. It exhibits the lowest vapour pressure and the highest tensile strength measured in standard tests.

Tungsten is used in high‐temperature applications. Its electrical conductivity is quantified and has been applied in high purity tungsten used in TFT-LCD displays.

The majority of tungsten is consumed in the production of tungsten carbide (WC), a carbide with one of the highest measured hardness values. Engineers use tungsten alloys in lamp filaments, electrical contacts, arc welding electrodes, radiation shielding and in the aerospace sector.

Tungsten (W) Properties

Tungsten is classified as a heavy metal and exhibits several quantified properties that support its use in various industries.

High Melting Point: Tungsten has the highest melting point among elements; consequently, it is applied in operations at extreme temperatures.

High Strength and Density: Tungsten provides high strength and density. Engineers select tungsten for components that must maintain mechanical stability under significant load.

Corrosion Resistance: Tungsten exhibits natural corrosion resistance. Given that it endures harsh conditions, it is used in chemical processing, aerospace and automotive sectors.

Electrical Conductivity: Tungsten conducts electricity reliably. This property is utilised in components where both conductivity and mechanical strength are required.

Radiation Shielding: Tungsten’s density qualifies it for radiation shielding. It is applied in healthcare, nuclear applications and scientific research.
