Ultra-high Melting Point (3422°C): This is the core advantage of tungsten tubes. In ultra-high-temperature vacuum or inert gas environments, they can maintain structural integrity and are used as heating elements, heat shields, crucibles or furnace tubes for high-temperature furnaces.
Ultra-high Density (19.3 g/cm³): The tubular structure provides excellent radiation shielding (against X-rays and gamma rays) with a relatively light weight. It is widely used for radiation collimation and shielding in medical equipment (e.g., CT scanner collimators), nuclear industry and security inspection devices.
Excellent High-temperature Strength and Creep Resistance: It is not prone to deformation or sagging at high temperatures, ensuring dimensional stability during long-term operation.
Good Thermal Conductivity and Low Thermal Expansion Coefficient: Suitable for thermal management components requiring rapid heat dissipation and dimensional stability.
Excellent Corrosion Resistance: It has good resistance to most acids, alkalis and molten metals (e.g., liquid zinc, tin, bismuth), and can be used as corrosion-resistant containers, electrodes and delivery tubes.
Tungsten Tubes for High-temperature Furnaces
Heating Elements: Directly heated by electricity in high-temperature furnaces under vacuum or hydrogen protection, with an operating temperature up to 3000°C.
Furnace Tubes/Heat Shields: Serve as high-temperature reaction chambers to protect peripheral components.
Sintering Boats/Crucibles: Used in sapphire single crystal growth, silicon carbide sintering, and high-temperature heat treatment.
Application Fields: Semiconductor, photovoltaic, laser crystal, and ultra-high-temperature material preparation.
Tungsten Tubes for Radiation Shielding and Collimation
Collimators: In medical CT, PET-CT, and linear accelerators, tungsten tube arrays are used to precisely define the shape and direction of radiation beams, improving imaging quality.
Shielding Sleeves: Protect sensitive components in nuclear facilities or detection equipment.
Features: Usually designed with high precision, thin wall,s and porous array structures.
Tungsten Tubes for Corrosion-resistant Component
Liquid Metal Containers/Delivery Tubes: Used for smelting, purificatio,n and transportation of low-melting-point metals such as zinc, tin, and bismuth.
Electrochemical Electrode Sleeves: Operate in highly corrosive electrolytes.
Tungsten Tubes for Military and Aerospace Applications
Rocket Nozzle Liners: Withstand scouring by high-temperature and high-velocity combustion gases.
Armor-piercing Projectile Core Material: Taking advantage of its high-density characteristic, but it is usually in the form of solid rods, and tubular versions are relatively rare.
Tungsten Tubes for Heat Sinks and Thermal Management
Leveraging their high thermal conductivity, they are used in the heat dissipation structures of certain special electronic devices or lasers.
