Tungsten (W) has a density of 19.25 g/cm³, making it one of the densest metals.
The high density of tungsten has significant practical value, mainly in its excellent radiation shielding, high-temperature stability, mechanical properties, and electrical characteristics.
Due to its high density, tungsten effectively shields radiation, making it widely used in medical equipment and nuclear reactors.
Additionally, its high melting point and strength make it an ideal material for aerospace, military, and high-temperature industrial equipment, often used in the manufacture of jet engines, rocket nozzles, and other components.
Tungsten is also used in making metal cutting tools, drill bits, and molds, as its wear resistance and hardness enable it to withstand extreme pressure. Its high density and good electrical conductivity make tungsten perform excellently in electronic and electrical devices, such as filaments and electron tubes. Furthermore, tungsten is widely used in manufacturing ballistic materials, armor, and weapon components.
Comparison of the densities of various metals
Tungsten’s density is close to that of gold and uranium, far exceeding most other metals. This characteristic makes tungsten advantageous in applications that require high density and strength, especially in fields such as high-temperature, radiation shielding, and ballistic materials.
