What is tungsten wire and where is it used?

Tungsten wire belongs to the category of heat-resistant materials characterized by increased strength and resistance to rust, adverse effects of external factors and aggressive chemicals.

For the manufacture of tungsten wire - GOST 18903-73 - forged rods are used. In the course of drawing, a gradual decrease in the temperature regime is carried out. After that, the product is cleaned by annealing and electrolytic polishing.

The raw material for the manufacture of this type of wire products is the most refractory metal. This material is heat-resistant and durable, it is not afraid of acidic and alkaline environments. Such characteristics make it possible to use tungsten wire for the production of parts intended for operation under heating conditions, as a result of which they do not lose their original properties.

Mechanical parameters characteristic of this type of wire products (increased hardness, resistance to wear during heating, low value of thermal expansion), exceeding many similar materials, make tungsten products very popular.

This type of rolled metal is distinguished by a high modulus of elasticity, excellent ohmic resistance, and good thermal conductivity. It is a durable and reliable material that can withstand extreme operating conditions, making it indispensable in a variety of manufacturing industries.

There are several brands of such wire. The classification is carried out in accordance with the cross-sectional diameter and the percentage of tungsten in the material.

The wire diameter can be from 12.5 to 500 microns.

The most popular brand is VA. The BPH brand is used for the production of cathodes for electronic devices.

The brands of tungsten rolled metal VM, VT are also in demand.

Tungsten wire is used in various spheres of production and the national economy. It is used to make spirals and spring elements for incandescent light bulbs.

The tungsten-rhenium variety (BPH) is used for the production of traverses.

Tungsten is a refractory metal, therefore, wire products based on it are indispensable for creating resistance elements in heating devices. It is contained in thermoelectric converters, loop heaters.

The process of manufacturing tungsten rolled metal is rather complicated with the use of powder metallurgy techniques. It is very popular in the electrical and radio engineering industries. It is actively used in the creation of LCD television screens. The most demanded wire products are tungsten anhydride and obtained from the salts of this metal.

On its basis, parts of X-ray equipment are made, which, during operation, are subjected to vibrations and strong heating. Meshes and filtering mechanisms based on it are used in the chemical industry.

Many are interested in where to find tungsten wire at home. It is a component of all heating parts of household appliances.

It is present in old versions of irons, electric kettles. If you have an old fan heater at home, remove the wire strands from the heaters.It's easy to get it out of broken toasters. It is also found in the heating elements of washbasins. To remove the wire, the heating elements are carefully opened with a grinder. It will only be necessary to clear the wire products from insulation.
