Relevance

Manufacture of wire by the powder metallurgy method, intended for the production of electronic devices and light sources. It is necessary to consider the complexity of processing, which is due to the exceptional refractoriness and hardness of the material. Also, the disadvantages of tungsten include the difficulty of mining it and obtaining pure material. Under natural conditions, tungsten is tough and brittle.

Advantages

High resistance to thermal creep, inertness in concentrated acids, alkalis and other aggressive media.

Production and applications

Tungsten wire is the most relevant product. Under normal circumstances, the technological ductility of tungsten is insufficient, but when the temperature increases, it increases without loss of strength. For this reason, the rolled product is obtained using the hot work method under pressure. The diameter of this product ranges from 25 to 1500 microns and is mainly used in the manufacture of cathodes for electronic, gas-discharge devices.

Delivery, price

All offered products are certified. The technical documentation includes data on the chemical composition and specifies the limiting percentage of impurities. The supplier " Evek GmbH ", delivers tungsten wire of standard and non-standard sizes at an affordable price in the shortest possible time from warehouses. The price of tungsten wire corresponds to the high quality of the product.
