Pure Tungsten Wire

In summary, tungsten wire is a versatile material that is widely used in multiple industrial and scientific fields due to its excellent high temperature properties and corrosion resistance.

Tungsten wire is usually used to manufacture electric light , electric vacuum components , the high temperature heating elements and high temperature furnace structural parts( like filament for all kinds of lamps) . The electropolishing tungsten wire are also used to produce tungsten spiral in the vacuum evaporation.

Yitechtrading produce and supply pure tungsten wire and other tungsten alloy wire (such as WRe alloy wire, WCu alloy wire and other tungsten alloy wire). Pure tungsten wire has the same properties of tungsten materials. The crystal structure of tungsten wire is even fine.

● Black wire with graphite

● Cleaned wire after pickling

● Electropolishing bright wire

As we all know, the electronic tube and bulb industry needs a tungsten wire with a smooth surface and no graphite coating. This "white wire" is usually obtained by cleaning. The cleaning methods include chemical or electrolytic polishing, acid or alkaline solutions. Among them, electropolishing tungsten wire solution is the best.

1. High Melting Point: Tungsten exhibits a very high melting point, about 3,422°C (6,192°F), which provides the capability of using pure tungsten wire where other metals would have melted.

2. High Strength: Pure tungsten wire is strong, with good mechanical properties, hence applicable at structural levels.

3. Electrical Conductivity: Tungsten is a good conductor of electricity, but it has higher resistivity than some other metals.

4. Thermal Conductivity: The thermal conductivity of Tungsten is quite good; it allows good heat transfer.

5. Low Thermal Expansion: The coefficient of thermal expansion for tungsten is relatively low; hence, tungsten does not expand very significantly with an increased temperature; therefore, pure tungsten wire will remain dimensionally stable.

6. Resistance to Corrosion: Tungsten resists corrosion by many acids and bases. It combines with strongly oxidizing acids.

Tungsten wire is used in many fields, such as in electronic devices, due to its very high melting point and electrical conductivity. Filaments used in incandescent light bulbs, electron-emitting filaments, and heating elements are made from pure tungsten wire.

Semiconductors: Pure tungsten wire is used in the semiconductor industry since such materials can resist high temperatures during their fabrication process.

- Cathode Ray Tubes: filaments are made of pure tungsten wire which, on being heated, emit electrons.

Pure tungsten wire used for medical applications, like in the equipment developed for radiation therapy, was based on the high melting point the material possesses and its resistance to radiation.

Aerospace: Few aerospace applications include rocket nozzles and re-entry shields, both because pure tungsten wires resist extremely high temperatures.

- High-Temperature Furnaces: pure tungsten wire is used in high-temperature furnaces since it is capable of conducting heat and bearing very high temperatures.
