​​​​​​​Application Advantages

The High Purity Tungsten Pipe is widely applied in industries that demand high-performance materials:

• Electronics and Semiconductors: Utilized in vacuum chambers, sputtering targets, and high-temperature semiconductor production.
• Aerospace and Defense: Suitable for components in aerospace engines, propulsion systems, and defense equipment requiring high mechanical strength.
• Metallurgy: Used in high-temperature crucibles, molten metal handling, and refractory processes due to excellent thermal properties.
• Scientific Research: Ideal for laboratories conducting high-temperature experiments, vacuum studies, and material science research.
• Energy and Environmental Engineering: Applied in reactors, heat exchangers, and other systems requiring long-term corrosion and heat resistance.

Manufacturing & Process Flow

​​​​​​​1.Moulding process: the density of the press block made by powder compacting is the 60~65% of theoretical density.

2.Presintering: under the temperature of 1200℃, the blank is put into hydrogen molybdenum wire furnace for 120min. After cooling to 250℃, move it away. After a presintering process can eliminate most of the adsorbed gas, thereby increasing the strength of th eproduct, which is conducive to the transport and the follow-up processes of sintered tungsten rod.

3.Vacuum sintering: sintering purpose is to increasing the purity and density, a sintering is a process of diffusing. Sintering temperature, atmosphere and holding time are the three main factors that affect the final product quality. If the product can be kept at 1650 ~ 1700℃, the metal impurities and gap elements would volatilize.

4. Cold processing: Cold processing of tungsten alloy pipes after hot processing, such as cold rolling, cold drawing, cold extrusion, etc., to improve their accuracy and surface quality.

5. Heat treatment: Heat treatment is performed on tungsten alloy pipes after cold processing to eliminate internal stress and improve their performance.
