Tungsten strip, foil are the final product. They are the thinnest sheets with a thickness of 0.03−0.09 mm. Tungsten strip, foil possess unique heat-resistance, insignificant coefficient of thermal expansion, high resistance to thermal creeping, good heat conductivity, high coefficient of electronic emission. Tungsten strip, foil have high module of tensile/compression, resistance to corrosion, effect of acids, alkalis, concentrated solutions of sulfuric, nitric, salt, chloronitric acids. Chemical resistance, strength, biological safety make tungsten foil an indispensable material in different industries.

There are a few demerits:
— difficulty of tungsten obtaining in pure state;
— high volume weight (as gold has);
— brittleness at low temperature. Due to its unique properties, it can be processed (rolled, drawn, forged) only after heating up.


Tungsten strip, foil are manufactured out of certificated high-quality tungsten of 99.95% purity by «cold-hot» method on close control equipment. As long as hot tungsten reacts with atmospheric gas, there are used the most modern technologies of chemical protection.

In order to obtain tungsten billet (bar), there is used powder metallurgy method. Then, billet must be heated and hammered on forging rotary machine to the form of thin sheet. After hot drawing, there is obtained a foil. After transformation of sheet into foil, rolling can continue without additional heating. Foil has smooth surface. Oxydes are deleted with hot solution of caustic soda or by ignition (t° 1000°C) in hydrogen atmosphere. Manufacturing quality control is performed at all steps of manufacture.


Rapid development of modern robot technologies, instrument engineering, nuclear energetics, mechanical engineering, petrochemical industry, medicine increases demand for foil made out of refractory metals. Tungsten strip, foil are used most often in:

— military-industrial complex;

— nuclear energetics;

— radiotechniques, electronics;

— industrial chemical synthesis;

— manufacture of thermal screens.
