Tungsten filament for light souce

Tungsten filament Bless produce was widely used for light source and element in semicondutor. Also, it is used as evporation source for spray coating. Such as high temperature lamp filament, stock-resistance filament, doubles helix filament, electric incandescent lamp filament, and fluorescent light filament, but also used as element in semiconductor, x-ray source, x-ray detector.

Tungsten filament type

Tungsten filament in lots of shapes, such as coiling, horizontal helix, and vertical helix, and so on could be produced by us, we also supply customized filament according to clents’ requirements.

Complete technology and samples support is our big advantages, we accept multiple modulation and finally help to finish the samples test successfully.

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.

 

. Equipment

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.

 

. Property

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

 

. Straightness
