Key Advantages of Tungsten Threaded Rods
3410 °C Refractory Heat Resistance
Extreme melting point prevents studs from softening, sagging, or melting in high-vacuum heating zones.
High Radiation Shielding
Ultra-dense atomic structure (19.30 g/cm³) blocks X-rays and gamma radiation in medical and nuclear assemblies.
Low Thermal Expansion
Minimal dimensional change under rapid heating prevents thread binding and joint deformation.
Cleanroom Vacuum Stability
Ultra-low vapor pressure prevents outgassing and chamber contamination during semiconductor processing.

Frequently Asked Questions
Pure tungsten threaded bars excel in high-vacuum furnaces, inert gas environments, semiconductor hot zones, and nuclear radiation shielding assemblies operating at elevated temperatures.
Tungsten oxidizes rapidly in air at temperatures above 400 °C. Operating in a vacuum or under inert gases (like Argon or Helium) prevents oxidation and thermal degradation.
