Quick Details
Specifications
Feature of Tungsten tube
1.the surface of tungsten tube is silver gray metallic luster;
2.the purity is no less than 99.95%;
3.Its density is more than or equals to 18.8g/cm3;
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.
FAQ:
Q: What information should I let you know if i want to get a quotation?
A: the required material dimension (Thickness*Width*Length,diameter*length; if possible, please kindly supply us drawings).
the required more information, such as Surface Condition, Tolerance Request, the Quantity, and other mechanical and technical details.
If it is possible, please also provide the application of products, we will recommend the most suitable products with details for confirmation.
Q: how do you gurantee the quality of the products?
A: Each step of production and finished products will be carried out inspection by QC department before storing in the warehouse. NG goods are not allowed in the completed goods warehouse.
Q: Can you guarantee the prompt delivery?
