About Tungsten

Tungsten (W), also called Wolfram is a silver-grey metallic element with the highest melting point of any metal (3410° C). Tungsten has a high density, high strength at elevated temperatures and extreme hardness. It is able to withstand tremendous force at elevated temperatures, is highly resistant to corrosion and offers good thermal and electrical conductivity. Tungsten metal is the hardest of the refractory metals, while tungsten carbide is one of the hardest known substances.

Tungsten Uses

Hardness:
Critical component of cutting tools used to drill or cut other metals, concrete or rock.

Temperature Resistance:
Critical component of temperature sensitive and wear resistant machinery, in electronics electronics and as a contact point in electrical circuits.

High Density:
Suitable as a weight or counterbalance in specific machinery applications.

Examples
Metal fabrication tools, snow tyre studs, engine valves, LCD panels, TV tubes, laser printers, window heating wire, electrical switch gear, airplane flaps, mobile phone vibration systems, golf clubs and as an environmentally acceptable substitute for lead shot in cartridges.

Tungsten Production
45-55% Hardmetals
15-20% Steel Alloys
10-20% Mill Products
15-20% Chemical Industry

Pricing
US$20,075/t (WO3 ore, as of September 29, 2008)
Sources of Tungsten Prices:
Metal Bulletin (UK)
Platts Metals Week (USA)

Note
Unlike the precious and base metals, there is no terminal market for tungsten. Trade is conducted , partially on undisclosed supply contracts between the primary producers, secondary processors and tertiary manufacturers, and partially via traders working both as agents and as principals.
