• Our warehouse currently stocks ultra fine tungsten wire with diameters ranging from 15μm to 50μm, available for fast delivery. With a minimum order quantity of only 1 km, our tungsten wire is ideal for customers who require small-batch sourcing, R&D trials, or stable long-term supply.

Black Tungsten Wire 99.95% D5-1800um, regularly black covered with graphite coating, has high melting point of 3422° C, low of thermal expansion coefficient, low vapor pressure, good electrical and thermal conductivity. It is essential for the production of lighting products such as single or double spiral lamp wire, fluorescence lamp wire, energy-saving lamp wire, single-end halogen lamp wire, Hi-temp lamp wire, twisted tungsten wire, tungsten heating element etc.

White Tungsten Wire or Cleaned Tungsten Wire, 99.95% D5-1800um, metallic luster surface after surface graphite removal, is of uniform in diameter, stress release, improved winding and Hi-temp properties. Cleaned tungsten wire is replacing black tungsten wire for the production of coiled incandescent lamp filaments, cathode and support structures for power tubes, filaments for auto lamps, fluorescent lamps, high pressure halogen lamps, heating elements and evaporation sources in metalizing processes etc.
