High purity tungsten tubes are designed for extreme high-temperature environments where excellent thermal stability, strength and long service life are required. They are widely used in vacuum furnaces, W-Re thermocouple protection, sapphire crystal growth, semiconductor equipment and other demanding industrial applications. Custom sizes, wall thicknesses and machining services are available.

Product Overview

High Purity Tungsten Tubes for Demanding Industrial Applications

ZSWMO manufactures high purity tungsten tubes with a purity of 99.95% or higher, engineered for operation in extremely high-temperature and vacuum environments. Thanks to tungsten's exceptional melting point (3422°C), low vapor pressure and excellent mechanical strength, our tungsten tubes maintain outstanding dimensional stability and reliable performance under severe thermal conditions.

Our seamless and machined tungsten tubes are widely used in vacuum furnace systems, W-Re thermocouple protection assemblies, sapphire crystal growth equipment, semiconductor manufacturing, powder metallurgy and aerospace applications. Whether you require standard dimensions or fully customized specifications, our engineering team can manufacture tubes according to your drawings or technical requirements.
