Description
About Tungsten wire
High-Temperature Heating & Furnace Grade
Industrial Tungsten Wire is a refractory metal heating material used in high-temperature furnace systems, vacuum thermal processing equipment, and precision resistive heating assemblies. With a melting point above 3400 °C and excellent creep resistance at elevated temperatures, tungsten wire remains one of the most reliable heating conductors for extreme industrial environments.
Manufactured from high-purity tungsten (≥99.95%) and produced in accordance with ASTM F288 or equivalent industrial standards, this Industrial Tungsten Wire delivers stable electrical resistance, long service life, and consistent performance in vacuum and inert-gas furnace applications.
