Tungsten rhenium wire has a series of excellent properties, such as high melting point, high strength, high hardness, high plasticity, high recrystallization temperature, high resistivity, low vapor pressure, low electron work function and low plasticity-brittle transition temperature, etc. In addition to the above properties of tungsten-rhenium alloy, low-rhenium alloy and high-rhenium alloy wire are matched to form a thermocouple with high thermoelectric potential value. The relationship between thermoelectric potential and temperature of various types of tungsten-rhenium thermocouples.

1. The distribution of rhenium in Tungsten rhenium wire is uniform, and the fluctuation range of rhenium content is controlled at 30.15%.
2. The single weight of billet is 3Kg.
3. To a diameter of 0.39mm, the yield of Tungsten rhenium wire is not less than 75%.
4. The diameter of Tungsten rhenium wire filaments is uniform.
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.
