Product Description
99.95% High Purity Various Dimensions Tungsten Pipe/tube hot sale in stock supplier manufacturer from baoji tianbo company
Tungsten based composites are strong refractory metal materials manufactured by a strictly controlled process involving pressing, sintering and infiltrating with copper or silver. They are highly resistant to heat, electric arc, wear and deformation at high temperature welding, flash butt and spot welding. They also have excellent electrical and thermal conductivity. The properties of Tungsten composites are related to the copper/silver-to-Tungsten ratio. If the Tungsten content improves, the electric arc and wear resistance will increase while the thermal and electrical conductivity, on the contrary, reduce.
Due to their unique properties, Tungsten based composites are widely used where the combination of good electrical and/or thermal conductivity and low thermal deformation is necessary, for example:
In electric resistance welding as electrical contacts or heat sinks.
In electrodes for electrical discharge machining (EDM) and electrochemical machining (ECM)

Features of Tungsten Pipe
1.high melting point, high strength,
2.outstanding thermal conductivity,
3.excellent resistance to electrochemical corrosion,excellent resistance to oxidation at high temperatures
4.The production processes of tungsten tube include isostatic pressing, IF induction sintering, CNC vertical turning, CNC milling, coreless grinder and wire cutting;
5.The tungsten tubes we produced are with high-precision, finish surface, straight size, and high temperature deformation.
6.There are two kinds of tungsten tubes: one is with diameter 8--70 mm, wall thickness more than 3mm, maximum length 300mm and density no less than 18.8g/cm3. Another one is with diameter 70—500mm, wall thickness more than 8mm, maximum length 700mm and density no less than 18.3g/cm3.

Application
Tungsten tube is widely used in the thermocouple protection tube, sapphire crystal furnace and high temperature furnace, etc. Tungsten is usually sintered processed and with 8mm wall thickness. Tungsten tube contributes stability to the hot zone. While high in thermal inertia, tungsten tube may prolong the growth cycle of the sapphire. The maximum wall thickness of one that rolled from tungsten plate is 2mm with low thermal inertia. But they are not as reliable and durable as normal ones.
