Products from tungsten-containing alloys

Description Specifications

Products from tungsten-containing alloys are widely used in many industries. The main application areas of tungsten alloys are conditioned by their key properties. Tungsten alloys provide high radiation protection due to its high density (tungsten alloys are at least 1,5 times heavier than lead). This is the reason why tungsten alloys are duly considered as the best material to protect from gamma-radiation in comparison with traditional lead, steel, water and cast iron. Moreover, tungsten has unique combination of qualities and properties enabling to use it at extremely high temperatures. Therefore, products made of tungsten-containing alloys are widely used in many industries.

Properties:

High alloy density;
High radiation resistance;
High durability;
High strength;
Heat strength and heat resistance;
Minimalcorrosionsensitivity;
Available cost.

Application:

Parts for radioactivity logging devices;
Storage vessels for radioactive agents;
Protective shrouds;
Collimators;
Elements of non-destructive control hardware;
Radiation-measuring and radiation control equipment etc.

The following alloys are the most widely used: tungsten-nickel-iron, tungsten-copper, tungsten carbide. Copper, nickel and iron combined with tungsten enhance the plasticity and electric conductivity of the material, as well as its machinability.

Alternative ratio or tungsten carbide and cobalt is possible, when so requested by Customer.

The “NPO “GKMP” LLC ОООsupplies pieces from hard tungsten-containing alloys: plates, couplings, shafts etc. per Customer’s drawings, as well as thermocouple rod ВР5/ВР20.
