Disc tungsten

Disc tungsten

The advantage of tungsten disc

The advantages of tungsten disk applies exceptional heat resistance (temperature is PL. of tungsten is +3422°C), high temperature creep resistance, high elastic modulus, the minimum coefficient of thermal expansion in comparison with other metals, resistance to aggressive agents and corrosion resistance, strength, durability and reliability.

Physical quality
The temperature at which the obtained data the features of t°C 20°C
The linear thermal expansion coefficient α [1/Deg] 43x10-6
The density of the alloy [g/cm3] 19,3
Tensile strength tensile kg/mm2 35
Specific heat at 20 °C [kJ/(kg·deg)] 0,134
The thermal conductivity K [W/(m·K)] 300,173
Electrical resistivity R, Mhmm2/m 0,054


The drawbacks include the difficulty of obtaining tungsten in its pure form, a large proportion (like gold) and brittle at low temperature. The tungsten disk is not enough plastic and hard at ordinary temperatures. Tungsten disk because of its exceptional properties to process (rolling, drawing and forging) only with considerable heat.


Tungsten disc is manufactured by sintering with subsequent machining. Refractoriness and a method of manufacturing a material guarantee high operational reliability and heat resistance of the disk. Disks produce any shape and parameters. Tolerances and dimensions are agreed with the customer. The cost of the discs from tungsten depends on the complexity of the configuration, the additional requirements of the customer and sizes. Quality products are standardized specifications. Tungsten disks are used as structural elements in silicon power semiconductor devices.
