Tungsten Spooled Wire
Goodfellow’s tungsten spooled wire, also known as tungsten drawing wire or tungsten filament wire, is manufactured from high-purity tungsten and designed to meet the stringent demands of advanced engineering applications. This product exhibits exceptional high-temperature stability in a non-oxidizing atmosphere with a melting point near 3,422°C (6,192°F), impressive tensile strength, and excellent resistance to corrosion and thermal creep, making it ideal for use in extreme environments. Goodfellow’s tungsten wire is widely employed in a variety of industries including aerospace and industrial manufacturing as well as in high-temperature heating elements, incandescent light bulb filaments, and welding electrodes. Its superior electrical and thermal conductivities, along with consistent performance under severe thermal and mechanical stress, position it as a critical material for precision applications, energy-efficient lighting solutions, and sophisticated thermal management systems in today’s cutting-edge technologies.
