Tungsten wire can be used to make electric light source parts and electric vacuum components, heating elements, refractory parts in high-temperature furnaces, and heating elements used in vacuum metallization or electroplating. Edgetech Industries LLC also offers regular and stranded tungsten wire for vacuum metal plating in various specifications upon request.

Process for tungsten wire: Drawing from tungsten rods, many times with annealing each time.

Performance and features of our tungsten wire

High-Temperature Performance: High-temperature performance requirements are classified based on the specific application.

Diameter consistency: The weight deviation of two consecutive 200mm filaments is less than 0.5% of the nominal value.

Our tungsten wire straightness:

Ordinary tungsten wire: upon request.

Straightening tungsten wire: For tungsten wires thinner than 100μm, the vertical height of the 500mm free-hanging wire should be no less than 450mm; for tungsten wires 100μm and above thick, the maximum arc height between two pints 100mm apart is 10mm.

Surface condition: Smooth surface, no cracks, burrs, cracks, dents, dots, grease pollution.

Coiling ability: No cracks or breaks during the coiling process.

Single piece weight: fine tungsten wire can reach 5kg, ordinary tungsten wire can reach 10 kg.
