Tungsten – the black gold

Focus on one of the hardest metals in the world

Tungsten is a chemical element with the symbol W and the atomic number 74. It is known internationally as tungsten. This extremely dense metal is a grey powder in its pure state; the sintered material is not deformable when cold and at normal temperature tungsten has a brittle consistency. Carbon and oxygen give tungsten its enormous hardness and also its brittleness, thanks to which the element is easy to process. The density is similar to that of gold. At 19.25 grams per cm³, tungsten is one of the heaviest metals.

Tungsten’s properties

Very good conductivity of heat and electricity
Good corrosion resistance
Superconductivity at low temperatures
An environmentally friendly metal that does not decompose
Very high density
Highest melting and boiling temperature of all metals
Very high modulus of elasticity
 Highest tensile strength at temperatures above 1,650 °C

Good to know

Tungsten is irreplaceable when high temperatures stress the material. At temperatures between 1,000 and 1,600°C, semi-finished products obtain their basic shape by means of forging, round hammering or rolling. Work pieces with very low tolerances can be made by a subsequent surface grinding operation. Alloy additives can be used to influence the chemical, physical and mechanical properties of our Litty semi-finished and finished parts.

Tungsten use

Used in many ways, tungsten has special properties. Among metals, tungsten has long been a household name, namely because of its use in light bulbs. The metal’s high heat resistance brought about a breakthrough in the development of artificial light sources. A light bulb’s filaments were made of tungsten wire.

Tungsten in metal processing

As an alloying element for steel, cutting tools, casting moulds and much more. Tungsten is also indispensable in mechanical engineering, medical technology and many other industries. In addition, tungsten is used in the construction sector, in high-temperature furnace construction and in electrical engineering. And of course in welding electrodes, which are also available from Litty.

Where is tungsten used?

It is found, for example, in the vibration alarm of mobile phones, in electric cars, as a flywheel mass, for die-casting moulds, in the jewellery industry, but also in drilling and milling inserts of industrial machines in automobile production. Many industries process tungsten. You’d like to find out more?
