Tungsten black wire is mainly used for the production of coil incandescent lamp filament, electric vacuum cathode and support structure, heating element in high temperature furnace and evaporation source of gold plating process.
Tungsten black wire can be used to manufacture electric light source and electrical vacuum parts. It is also applied as high temperature heating element and high temperature structural parts and used to make tungsten screw for vacuum evaporation. Thicker tungsten wire, through straightening, grinding surface, and cut into bars, widely used as glass metal seal parts applied in lighting and electronic industry.
Black tungsten wire has the advantages of good thermal deformation resistance in high temperature, high recrystallization temperature, good diameter uniformity and consistency of wire coiling.
We could offer ground tungsten wire and black tungsten wire according to your need. Any enquiry, please feel free to contact us!
