Tungsten is known in the world as the most refractory metal, which makes it the basis for the most heat-resistant alloys. The electrical conductivity of tungsten is three times lower than that of copper. Among his Wolframovaya setka - Tungsten mesh of flaws, a high density, increased cold brittleness, and low oxidation resistance even at low temperatures are noted. Tungsten is subject to processing only when heated to a certain temperature. This temperature is determined depending on the type of processing (forging, rolling or drawing).
Tungsten mesh is made from tungsten wire. Its manufacture is carried out by drawing at a temperature of 1000 at the beginning, and 400 at the end. After this treatment, the surface of the wire is coated with graphite grease and must be cleaned. Cleaning is carried out using annealing, electrolytic or chemical etching, as well as electrolytic polishing (the mechanical strength of the wire increases by 25%). A tungsten mesh is made from several types of tungsten wire:
1. VA group AP with a diameter of 10-200 microns with a black state of the metal;
2. VA group G, diameter - 11-500 microns, the surface is cleaned and annealed;
3. VA group T with a diameter of 5-12 microns, etched surface;
4. VA group TO, diameter - 5-12 microns, the surface is etched and annealed.

Tungsten wire mesh is made of 99.9% tungsten wire and has extremely high tensile strength. Tungsten has the highest melting point among all metals, even at temperatures above 1650 ° C. Among its properties are a melting point of 3410oC, low coefficient of thermal expansion and good electrical and thermal conductivity.

The tungsten wire mesh is highly resistant to corrosion and has a high density, sufficient electrical resistance, high elastic modulus, low vapor pressure and low thermal expansion combined with good thermal conductivity.

Type of mesh weaving: plain, twill ..
Materials: W1, W2, WAL1, WAL2 and WAL3. (Shiny pure tungsten wire, tungsten content ≧ 99.95%, black pure tungsten wire.)
Wire diameter: from 0.05 mm to 2.0 mm.
The number of cells per square. inch: from 2 to 200 at usual weaving.

Application:
Electromagnetic shielding grid, vacuum furnace for heat treatment, electronic protection, light filter. A tungsten wire mesh is often used to provide conductivity to heat and electricity, as well as to absorb radioactive radiation and X-rays. The tungsten wire mesh is characterized by high heat resistance and is often used as a heating element in a vacuum furnace, as well as for heat treatment processes. Tungsten wire cloth is used to produce batteries, chemicals, mines, hydrogen production, acid production, etc.
The tungsten mesh has found its application in the electronic industry, in grinding surfaces, in the chemical industry, a tungsten mesh is used for the manufacture of all kinds of filters, etc..
