Tungsten wire mesh

Tungsten wire mesh

Supplier — AvekGlob Company — offers tungsten braided mesh at an affordable price from the manufacturer. The supplier guarantees the timely delivery of products to any address specified by the consumer.

Technical specifications

Tungsten braided nets are characterized by high-temperature strength. Tungsten has the largest tensile strength among the known metals and the minimum vapor pressure. To produce the mesh, tungsten is used with a chemical purity of 99.9%. According to the generally accepted production technology, tungsten is extracted from ores, crushed to the powder stage, and then molded and stretched into a wire, which is the basis of a woven mesh, to create a wire mesh.

Features — high fire resistance (more than 1650 ° C), extremely high heat of vaporization, good electrical and thermal conductivity, high density under mechanical loads, not changing with temperature increase, low coefficient of thermal expansion.

Urgency of application

Tungsten braided mesh is used in applications where corrosion resistance, resistance to chemically aggressive media, fire resistance, high mechanical pressures and high-temperature strength are important. The most such grid is in demand in the chemical industry, in the production of ferric acids and alkalis, in mining, in the production of powerful batteries and hydrogen.

Chemical composition of mesh material

For the production of nets of various accuracy in domestic production, wire is used from tungsten VA in accordance with GOST 18903−73, GOST 19671−91, which contains:

Tungsten — 99.95%;

Aluminum — 0,001… .0,004%;

Silicon — 0.001… 0.006%;

Molybdenum — up to 0,03%;

Calcium — up to 0,005%;

Iron — up to 0,005%.

Assortment

The standard parameters of tungsten braided nets are:

Roll width, mm — 1000… 2000;

The dimensions of the cells, μm — 220… 2000;

Step, μm — 40… 200;

Length of the roll, m — 2… 7.

Supplier — AvekGlob Company — offers to purchase tungsten braided mesh in any quantity and at any size of cells. Products can be bought at a price formed on the basis of European and world standards of production. Implementation is possible in bulk and retail, for regular customers, a flexible system of discounts operates.
