Tungsten sheet
Tungsten is the most refractory metal on the planet, so its use goes far
beyond the usual alloys. For example, if you make a sheet of it,
tungsten becomes a reliable protection against huge temperatures, being
the top shell of powerful thermal insulation. These sheets are extremely
difficult to manufacture, because the basic technology for their
production is not rolling, but sintering in specialized powder furnaces
at high temperatures. Tungsten sheet should be distinguished from
tungsten plates, which have a completely different scope. The difference
is primarily in thickness. The plates are smaller and thicker, and the
manufacturing process is much simpler.
Where sheet and plates are used
Tungsten sheet found its main application in the chemical industry due
to its extreme resistance to corrosion even under the influence of high
temperatures. Under normal conditions, tungsten does not react in any
way to concentrated organic acids, and in order for the minimum reaction
to go, heating is necessary to at least 100 degrees Celsius. Therefore,
tungsten sheets and plates are used to create reliable protection, as
well as for metal highly reliable containers used for transportation of
aggressive environments.
Testing equipment for measuring the concentration of aggressive
substances in solutions and melts is made from the same sheet. They also
make hollow electrodes for plasmatron research and work.
The price of a tungsten sheet depends on its thickness and area. It can
be formed both on a piece product, and have a cost per 1 kg of molded
metal.
Tungsten sheet and tungsten plates are used for shielding and
manufacturing other elements of vacuum furnaces operating at extremely
high temperatures.
Tungsten plates and sheets Tungsten plates and blanks
Tungsten sheet is a component of the plasma torch electrodes and devices
involved in measuring the concentration of aggressive chemical
solutions. This metal is not prone to corrosion and can withstand any
environmental influences.
In order for tungsten to enter a minimal reaction with aggressive acids
- sulfuric, nitric and even hydrofluoric - it must be heated to 100 ° C.
The reaction with oxygen is possible after the temperature of tungsten
becomes higher than 400 ° C, with water vapor - at 600 ° C.
