Tungsten, also called Wolfram occurs as an impure tungsten oxide in wolframite and scheelite ores. Tungsten is the only metal from the third transition series that is known to occur in biomolecules, where it is used in a few species of bacteria and archaea. It is the heaviest element known to be essential to any living organism. It is chemically extracted, refined to an oxide of high purity and reduced to tungsten powder in hydrogen atmosphere furnaces.

Tungsten has the highest melting point of approximately 3422 Celsius and the lowest coefficient of expansion and lowest vapor pressure of any commonly used metal. Its density, similar to that of gold, allows tungsten to be used in jewelry as an alternative to gold or platinum.
Approximately half of the tungsten is consumed for the production of hard materials – namely tungsten carbide – with the remaining major use being in alloys and steels.
The hardness and density of tungsten are applied in obtaining heavy metal alloys. A good example is high speed steel, which can contain as much as 18% tungsten.Tungsten's high melting point makes tungsten a good material for applications like rocket nozzles.

Machining tungusten in our cnc machine shop:
Tungusten's properties provide it with excellent resistance to sticking or welding, and outstanding resistance to metal transfer and electrical erosion caused by arcing. Its high hardness and strength make it highly resistant to mechanical wear and deformation where the contacts operate with high closed forces and at high repetitive rates. In high humidity atmospheres, tungsten is susceptible to electrochemical corrosion. We use 5 axis machines such as Haas UMC 750 and Haas VF-5SS as well as conventional milling equipment (Matsuura RA-1G, MC 500V PC 2S and MC-510 VG)

Application:
Some of the applications include vibrating devices such as automotive horn, magneto ignition and motor speed governor contacts. In other applications, tungsten is selected only for its high resistance to arc erosion. It can be found also in semi-conductor bases and glass seals because of its low thermal expansion and for applications where low arc erosion and anti-weld characteristics are important. Some of the applications include vibrating devices such as automotive horn, magneto ignition and motor speed governor contacts. Tungsten alloys are used in a wide range of different applications, including the aerospace and automotive industries and radiation shielding. Superalloys containing tungsten, such as Hastelloy and Stellite, are used in turbine blades and wear-resistant parts and coatings.
