High temperature WRE5/26 tungsten rhenium thermocouple wire

High temperature WRE5/26 tungsten rhenium thermocouple wire Tungsten rhenium thermocouple wire
Tungsten-rhenium wire is tungsten rhenium alloy wire, made by metal rhenium powder and tungsten powder. Through production processes. such as forging etc. with powder metallurgy technology.
Tungsten-rhenium wire are mainly used for the production of dual tungsten rhenium wire, electrode of high-performance lamp, electrodes of laser and cathode of electron tube etc.
The wires is solid, round, smooth and be free of weld joints, slivers, kinks, pits or nicks exceeding 5 % of diameter . Tungsten rhenium wire surface is uniformly clean and free of discoloration. The thermo elements is heat treated to provide the specified ductility.
Tungsten-rhenium wire is the most common material used to produce heaters for dispenser cathodes. Performance variation may be attributable to a range of factors, including cold work and rhenium content varia
Compared with pure Tungsten, Tungsten Rhenium Alloy not only has the properties of good ductility and low plastic-brittle transition temperature but also has the properties of high tensile strength, creep strength and recrystallization temperature. Its comprehensive properties are excellent. Generally, with the increase of rhenium, the strength of Tungsten Rhenium Alloy increases.
Tungsten Rhenium Alloy is often made into alloy wire. In room temperature, it has the advantage of high strength in high temperature, good ductility after recrystalization, high resistivity, oxidation and carbonation resistant, good capability of anit- "water cycle response" and good welding property. Tungsten Rhenium Wire: The melting point of the tungsten rhenium alloy thermocouple wire is 3120~3360.The tungsten rhenium alloy thermocouple wire can be used reach up to the peak 3000,it can be used for making the most heat resistant metal thermocouple. It has high EMF,high sensitivity.It cant be dissolve in any isolated acid.The raw materials are abundant in China,and the price is cheap. Specification: 1.Name: WRe3-WRe25; WRe5-WRe26
