Tungsten

Chinatungsten Online is specialised in pure tungsten manufacturing and exporting in the past two decades, and we have supplied nearly all kinds of pure wolfram products with different shapes, e.g. wolfram wire, wolfram heater, wolfram bar, wolfram electrode, wolfram plate, wolfram sheet, wolfram target, wolfram needle, wolfram boat, wolfram crucible, wolfram contact, wolfram point etc.

We are very proud of our over twenty years' successful experiences of supplying high-quality pure tungsten products with great services at the most competitive prices.

wolfram heater with helix shape Wolfram crucible using in melting and sapphire industry wolfram electrode with green tip for welding
pure wolfram target with grounded surface wolfram filament and tungsten heater black wolfram wire with blace surface
wolfram evaporation boat wolfram lanthanated electrode with gold tip for welding wolfram disk with alkline cleaned surface

As a high performance material, wolfram products have high melting temperature (3,422 °C, 6,192 °F), high density (19.25g/cm3), low vapor pressure (at temperatures above 1,650 °C, 3,000 °F), low thermal expansion combined with good thermal conductivity, sufficient electrical resistance and high modulus of elasticity.

Pure wolfram products are widely used for furnace parts, semiconductor base plates, components for electron tubes, emission cathodes for electron beam evaporation, cathodes and anodes for ion implantation, tubes / boats for sintering of capacitors, targets for X-ray diagnostics, crucibles, heating elements, X-ray radiation shielding, sputtering targets and electrodes.

The most popular applications of the pure wolfram are the manufacturing of arch-welding electrodes, filaments for bulb lamps, heating elements in high temperature furnaces, etc.

Tungsten electrode, namely wolfram rod, including thorium wolfram electrode, cerium wolfram electrode, lanthanum wolfram electrode, zirconium wolfram electrode and yttrium wolfram electrode and pure wolfram electrode has been widely used in welding and used as cathode.

Tungsten filament is a product existed when the bulb with tungsten filament is invented and has a long history. Since tungsten filament has gone through so long history, it has been created with kinds of shapes to match different bulbs, such tungsten filament in the room, tungsten filament in the car, tungsten filament in the motorbike, and so on. All the applications has promoted tungsten filament to be more fashion and applicable.

Tungston, is a word which is used in searching for tungsten for the wrong spell. Even though tungsten is the correct writing, “tungston” is still widely used in the google searching, such as “tungston filament”, “tungston electrode”, “tungston wire”, “tungston rod”, “tungston heater”, etc. in the written and oral English, we recommend people around the world to use tungsten, which is the right word, to describe the metal.

We hope in our website you can find the right type(s), drawing(s) which may meet your requirement.
