Pure tungsten is a metallic element with the chemical symbol W and the atomic number 74. It is the heaviest metal that is commonly used as a commercial material. Tungsten is used in a wide range of applications, including in incandescent light bulbs, welding electrodes, and X-ray tubes.

Pure tungsten is a hard, brittle metal with a high melting point of 3422 °C (6192 °F). It has a high electrical conductivity, and is resistant to corrosion and oxidation. Tungsten is also very strong, with a tensile strength of 1510 MPa (220,000 psi).

Pure tungsten is not found naturally on Earth. It is obtained by reducing tungsten oxide with hydrogen gas. The resulting powder is then sintered into solid form.

Pure tungsten is used in a number of different industries, including:

* Electrical: Tungsten is used in incandescent light bulbs, as well as in electrodes for welding and X-ray tubes.

* Electronics: Tungsten is used in integrated circuits, transistors, and other electronic devices.

* Aerospace: Tungsten is used in high-temperature alloys for jet engines and rocket engines.

* Medical: Tungsten is used in surgical instruments and implants.

Pure tungsten is a versatile material that has a wide range of applications. Its unique properties make it an ideal choice for use in high-temperature, high-stress environments.
