Tungsten Heavy Metal Foil

Tungsten heavy metal has the highest melting point (3410°C or 6170°F) of all metals.  The extremely high melting point of pure tungsten makes all the common manufacturing techniques used for metals such as iron impractical. Specialized methods make possible the processing of pure tungsten into rod, sheet, and wire for a wide variety of high temperature applications including incandescent lamp wire, TIG welding electrodes, high temperature heat shielding, etc.

Tungsten heavy metal foil is a product of rolled tungsten heavy metal, so pure tungsten heavy metal foil has the properties of tungsten heavy metal such as heat resistance, good thermal conductivity, high tensile modulus and compression. Tungsten heavy metal foils are commonly used in aerospace, nuclear power industry and chemical industry.

Tungsten heavy metal foil and tungsten strip is extremely heat-proof and heat-resistant. It has small thermal expansion coefficient, high resistance to thermal creep, good thermal conductivity and high electron emission coefficient. Tungsten heavy metal foil is very solid; it has very high tensile modulus and compression. It is resistant to corrosion, the action of alkalis and acids, including concentrated hydrochloric, sulfuric and nitric acids, aqua regia, which makes tungsten foil suitable in various fields use.
Tungsten metal foil is widely applied in modern electronics, electrical instrumentation and robotics, mechanical engineering and nuclear power, chemical and petrochemical industries.
The most common application of tungsten foil:

in nuclear power and aerospace industries;

Inthe chemical industry
