Product Description

Tungsten-Rhenium Alloy Wire For Thermocouple

 

1. Tungsten Rhenium Alloy Wire for Thermocouple description:

 

Tungsten-rhenium thermocouple wire is a high temperature thermocouple. It benefits from a strong linear relationship between temperature and potential, dependable thermal stability, and an affordable price. It can directly monitor the temperature of liquid, steam, and gas mediums when paired with the display instrument. In vacuum, reducing, and inert atmosphere, it can be used in the range of 0 to 2300°C.

 

2. Classification of Tungsten Rhenium Alloy Wire For Thermocouple:

 

Grade W content% Re content% K content% Content of each impurity element % Total amount of impurity elements %
W-1Re balance 1.00±0.10 0.004-0.009 ≤ 0.01 ≤0.05
W-3Re 3.00±0.15

 

Tungsten-rhenium thermocouple wire grades are W/(W-26Re), (W-3Re)/(W-25Re), (W-5Re)/(W-26Re) and (W-5Re)/(W-20Re) Wait. The long-term use temperature is 2000 ~ 2400 ℃, and the short-term use can reach up to 3000 ℃.

3. Advantage of Tungsten Rhenium Alloy Wire For Thermocouple:

 

The advantages of tungsten-rhenium alloy wire include high strength both at low and high temperatures, good plasticity after recrystallization, high resistivity and low resistivity, resistance to oxidation and carbonization, strong resistance to the "water cycle reaction," and effective welding.

 

4. Performance of Tungsten Rhenium Alloy Wire For Thermocouple:

 

The good qualities of tungsten-rhenium alloy wire include high melting point, high strength, high hardness, high plasticity, high recrystallization temperature, high resistivity, low vapor pressure, low electron work function, and low plastic-brittle transition temperature, among others. The combination of low-rhenium alloy and high-rhenium alloy wire results in a thermocouple with a high thermoelectric potential value in addition to the tungsten-rhenium alloy's previously mentioned features. the correlation between temperature and thermoelectric potential in several tungsten-rhenium thermocouple types.

 

1) The rhenium content of tungsten-rhenium wire is evenly distributed, and its fluctuation range is kept at 30.15%;
2). The billet weighs 3 kg by itself;
3). To the diameter of 0.39mm, the yield of tungsten-rhenium wire is not less than 75%;
4). The diameter of the tungsten-rhenium filament is uniform.

 

5. Application of Tungsten Rhenium Alloy Wire For Thermocouple:

 

Tungsten Rhenium alloy 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.

 

4). To create a thermocouple, low-rhenium alloy and high-rhenium alloy wire are matched.


5). The low-rhenium alloy wire and the high-rhenium alloy wire are matched to form a thermocouple, with a wide temperature measurement range (0~2500C), high thermoelectric potential value, fast response speed, and good corrosion resistance. Therefore, tungsten-rhenium thermocouple wire is used in temperature measuring instruments. widely used in. It is not only used in vacuum, reducing atmosphere and inert atmosphere, but also used in oxidizing atmosphere instead of platinum-rhodium thermocouple for temperature measurement when anti-oxidation measures are taken.


6). It is used to manufacture single crystal sapphire for bundling.

 

7).Tungsten-rhenium wire also has two commonly used tungsten-rhenium alloys, 25%Re and 26%Re, which are mainly used as thermocouple materials! The tungsten-rhenium thermocouple's key benefits are: 1. Fast response speed. 2. Wide range of temperature measurement, up to 2500℃. However, it is generally used in an inert atmosphere or a reducing atmosphere, otherwise a protective casing is required, usually a Mo alloy casing.
