Tungsten rhenium wire manufacturers tell you that once the tungsten wire is recrystallized after being used at high temperature, it becomes very brittle, and it is very easy to break under impact or vibration. In some electric light source products that require high reliability, in order to prevent the filament from breaking, rhenium is often added to the doped tungsten wire, which is called Tungsten rhenium wire, and the alloy contains 1% to 5% rhenium (mass). Silicon, aluminum and potassium are added to improve the high temperature properties of the material. It can make the tungsten brittle transition temperature drop to room temperature or below.

Tungsten rhenium wire has the advantages of high strength at room temperature and high temperature, good plasticity after recrystallization, high resistivity, low resistivity, resistance to oxidation and carbonization, strong resistance to "water cycle reaction" and good welding performance.
Uses of Tungsten rhenium wire:
For color picture tube heating filaments, various electron tube filaments and grids.
1. Production of tungsten filament lamps and chromatographic heat sensitive components with special requirements;
2. It is used to manufacture heating wire mesh for TV heating and picture tube and camera tube;
3. For military electronic equipment.
