Thin Tungsten Wire
Thin Tungsten wire Bless provide is made of high quality tungsten raw materials, mainly used in the manufacture of tungsten yarn for safety gloves, tungsten filament for light source. Diamenter from 15um, 20um, 25um, 30um, 35um are mostly used by customer. We monitor the overall diameter uniformity and test the extension of the wire during process to ensure best performance.

Tungsten Wire Parameters & Tolerance
Strong Equipment, Strong Quality
·Swagging
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.
·Straightness
Ensure thin wire straightness, we use high technology "3 Point 1 line" from wire relief to mold, and receiving smoothly without any curve.
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.

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.
·Linearity:
·- 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's application Bless customer use
Tungsten Yarn for Safety / Protection Gloves & Tungsten Filament for light souce.
