Pure tungsten tube is a high-purity (≥99.95% W) refractory metal component designed for extreme temperature, vacuum, and corrosive environments, widely used in furnaces, semiconductor equipment, and aerospace systems.
Features
Ultra-High Temperature Resistance
With a melting point up to 3422°C, the tube maintains structural integrity and performance in extreme heat environments.
High Density & Strength
Density up to ~19.3 g/cm³ ensures excellent mechanical strength and makes it ideal for shielding and high-load applications.
Low Thermal Expansion
Minimizes deformation under thermal cycling, ensuring dimensional stability in precision applications.
Corrosion Resistance
Resistant to most acids and harsh environments, suitable for vacuum and chemical processing systems.
