Manufacture of tungsten steel

Manufacture of tungsten steel

Are you interested in the production of tungsten rolled products from the supplier company AvecGlob? Here you will find interesting information on this topic.

General requirements

Tungsten bulk and sheet products are made of high-purity tungsten powder. Because of the special properties of tungsten, the range of tungsten products is widely used for the manufacture of measuring elements and contacts, welding wire, high temperature screens, etc.

The chemical composition and properties of tungsten steel are determined by the following data:

physical characteristics
Density 19170 kg / m 3
Melting temperature 3410 ° C
Electrical Conductivity 5.5 μΩ / cm

The degree of chemical purity of tungsten, which is used for the manufacture of rolling profiles

Chemical composition
W: Not less than 99.95% Al: Not more than 25 PPM
C: Not more than 50 PPM Cr: Not more than 20 PPM
Cu: Not more than 15 PPM. Fe: Not more than 50 PPM
K: Not more than 30 PPM Mo: Not more than 50 PPM
Na: Not more than 20 PPM Ni: Not more than 50 PPM
O: Not more than 50 PPM Si: Not more than 25 PPM


Supplier — AvekGlob company — offers at different prices from the manufacturer different types of rolled products, made of tungsten of different purity. The supplier guarantees the timely delivery of products to any address specified by the consumer.

Urgency of application

Tungsten rolled products are widely used to produce products that must have high thermal stability, low thermal expansion and high electrical or thermal conductivity. Typical applications are responsible parts of jet engines and electrical devices. Tungsten rolled products are used for critical refractories, radiators, rocket parts, etc.

Sequence of production

Modern methods of processing tungsten billets include dissolving concentrates of celite and wolframite by alkaline digestion under pressure, using either soda or a concentrated solution of NaOH. The resulting solution of sodium tungstate is purified by precipitation and filtration,

before it turns into a solution of ammonium tungstate. This step is carried out solely by extraction with a solvent or ion-exchange resins. Finally, high-purity ammonium-paratungstate is obtained by crystallization.

Wolframite concentrates can also be melted directly with charcoal or coke in an electric arc furnace to produce ferrotungstate, which is used as an alloying material.

Supplier — AvekGlob company — offers to purchase tungsten rolled products of various assortments (circle, bar, wire, sheet, strip, etc.) of various applications. 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.
