Bless Tungsten wire advantages:


High temperature performance

According to different uses of customers, we can subdivide various high temperature performance requirements.


Diameter consistency

The weight difference between two consecutive 200mm sections of tungsten wire does not exceed 0.5% of the nominal specification.



- Ordinary tungsten wire:  National standard GB / T 23272-2009

Straightening tungsten wire

A. Diameter < 100 μm: 450mm natural droop height for per 500 mm wire segment;

B. Diameter ≥100μm:  the arc height ≤10mm per 100mm chord length.


Surface state

Smooth surface, no cracks, burrs, scratches, pits, unevenness, oil stains and other defects.


.Wire winding performance: 

During the wire winding process, the tungsten wire does not crack continuously.



What is the Tungsten wire used for:


Manufacturing of electric light sources and electric vacuum parts


Used as high-temperature heating elements and high-temperature structural parts
Used to make tungsten spiral for vacuum evaporation
For integrators, fume purifiers, electrostatic precipitators, air purifiers, printers, copiers, etc.
The surface of the tungsten wire is coated with graphite cream, which looks uniform black. It is metallic luster if remove graphite cream.

Quality Inspection


. Flaw Detection

Corresponding tests for each process of Tungsten wire. Under flaw detection, there are Grade A (2 crack points per 100 meters), B, C Grade. The more cracks, the more easily the filaments are broken during processing. We will choose different standard according different request for quality grade.



A rolling mill introduced from Germany, which it can be deeply process the rod core, which can make the inside struction more uniform. Unlike the early traditional technology, are mainly surface processing.



Online measuring device in the wire drawing process, which can monitor the overall diameter uniformity.
