src="image/tungsten_heater.jpg" alt="wolfram heater with helix shape" title="wolfram heater with helix shape"> <p align="justify">Pure tungsten metal is with theoretical purity 99.95% and density 19.25g/cm3. Chinatungsten Online is specialized in manufacturing and exporting in the past two decades, and 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.</p> <img style="padding-left:10px" align="right" src="image/tungsten-disk.jpg" alt="wolfram disk with alkline cleaned surface" title="wolfram disk with alkline cleaned surface"> <p align="justify">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. Whether the metal is shaped in disc or boat, or crucible, it will not change its density and high temperature resistance properties and mostly, the machining is done after sintering and/or forging. Wire cutting is using Ø0.18 molybdenum wire for the round outer circle or center hole.</p> <img style="padding-left:10px" align="right" src="image/Pure tungsten target.jpg" alt="pure wolfram target with grounded surface" title="pure wolfram target with grounded surface"> <p align="justify">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. Tungsten wire, plate, sheet, disc are popular types for the above application machining. Even though pure tungsten metal is brittle, but with years experience of machining, Chinatungsten can provide customized types for customized application. </p> <img style="padding-left:10px" align="right" src="image/Pure_tungsten_Electrode.jpg" alt="wolfram electrode with green tip for welding" title="wolfram electrode with green tip for welding"> <p>The most popular applications of pure wolfram are for producing 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 or anode. TIG and GTAW welding are the welding method for tungsten electrodes, no matter the rare earth doped. According to the different tip color, the grade of electrode can be identified.</p> <img align="right" src="image/tungsten_wire_3.jpg" alt="black wolfram wire with blace surface" title="black wolfram wire with blace surface"> <p>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. Wires are mostly with black and cleaned surface. Cleaned wire is removed graphite surface from black tungsten wire. With settled uses, wire can be doped for a longer life time purpose. The needle with small diameter can also cut from straightened tungsten wire.</p> <img align="right" style="padding-left:10px" src="image/Tungsten_Crucible.jpg" alt="wolfram crucible using in melting and sapphire industry" title="wolfram crucible using in melting and sapphire industry"> <p>Tungsten granule, used as flux, accelerator in carbon and sulfur analyzer, is one of popular products, with high purity and low content of C and S. Regular sizes can be -10~+20mesh, -20~+40mesh, and -40~+60mesh. Besides, 0.5~2.0mm is a popular method to describe the size of granule. In order to test the C and S content, for the high temperature resistance, tungsten crucible and tungsten boat with tungsten metal material are always used in analyzing as matched equipments. Crucible is calculated by sizes of the outer dimensions and the volume. With precise size, the use of granule can be much easier.</p> <img align="right" style="padding-left:10px" src="image/tungsten-evaporation-boat-1.jpg" alt="wolfram evaporation boat" title="wolfram evaporation boat"> <p>Customized products are welcomed for pricing. Most of wolfram parts can be designed and cooperated based on drawing, such as anode, cathode, nozzle, heater, nut, bolt, etc. Tungsten boat can be customized by its size and shape, also the producing methods, such as stamping boat, riveting boat, sintering boat, forging boat...The picture showed is a kind of stamping one, and is the most common and popular type for using in metal melting. Customized tungsten can be with standard size of steel material, such as screw and bolt, can use M3, M4 and other standards for processing tungsten. Besides the national standard for common use, drawing should be designed.</p> <img align="right" style="padding-left:10px"src="image/Lanthanated_Tungsten_Electrode.jpg" alt="wolfram lanthanated electrode with gold tip for welding" title="wolfram lanthanated electrode with gold tip for welding"> <p>Tungston, is a word used in searching for tungsten for the wrong spell, such as "tungston filament", "tungston electrode", "tungston rod", "tungston heater", etc. in the written and oral English, we recommend tungsten, which is the right word, to describe the metal. Besides the wrong words, there are many different languages to describe tungsten, such as volfram, wolf rahm, which are refined from wolframite or schelite. About 61,300 tonnes of tungsten concentrates were produced in the year 2009, and in 2010, world production of tungsten was about 68,000 tonnes. China has accounted for most largest amount quantity.<p> <img align="right" style="padding-left:10px" src="image/tungsten_heater/tungsten_heater_9.jpg" alt="tungsten heater" title="tungsten heater"> <p align="justify">We hope in our website you can find the right type(s), drawing(s) which may meet your requirement.
