Product Description

As a high performance material, Tungsten 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.
Tungsten Tube, also named wolfram tube is a main product of pure tungsten products, which is making with purity of 99.95%min. meanwhile, its density can be higher to 18.2g/cm3 for sintering and 19.2g/cm3 after swaging. With its high density, the product is widely used as shielding material. As for the material is also with tungsten properties, high melting point, high boiling point, high temperature resistance, corrosion resistance and low thermal expansion. The tube can be used as pipe in melting other metals.
Tungsten tube is making according to GB/T 4187-1984 in Chinese standard and international standard of ASTM F288-90. The physical and chemical properties can reach the attached parts as the basic standard.
The manufacturing process of the wolfram tube is using metallurgy: molding, sintering, swaging, grounding and inspection and packing.

RADIATION SHIELDING

Pure tungsten 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.
