Features of Tungsten Screws and Bolts
1. Extremely High Temperature Resistance
Tungsten has the highest melting point among metals (3420°C), allowing tungsten fasteners to maintain excellent mechanical properties under extreme temperature environments.
2. High Strength at Elevated Temperature
Compared with conventional metal fasteners, tungsten screws and bolts provide better stability in high-temperature vacuum and protective atmosphere environments.
3. High Density and Wear Resistance
Tungsten's high density and hardness make it suitable for demanding applications requiring durability and resistance to deformation.
4. Excellent Vacuum Compatibility
High purity tungsten produces very low vapor pressure, making tungsten fasteners ideal for vacuum furnace applications.
