Products Description
Tungsten rhenium wire is mainly used for binding in sapphire production furnaces. Tungsten rhenium wire is mainly made of tungsten rhenium wire with a rhenium content of 25%.
Tungsten can be added 3%, 5%, 25% and 26% of rhenium to form tungsten rhenium alloy for high temperature thermocouple wire and the cathode wire. It has good high-temperature ductility, used in the electronics industry, nuclear industry and aerospace industries.
The tungsten wire after recrystallization becomes very fragile when used at high temperatures. It is easy to break in a state of oscillation. In some high-performance electric light sources, rhenium is usually added to the tungsten wire to prevent filament breakage. Tungsten rhenium wire can extend the brittleness of tungsten at lower temperatures, even at room temperature or lower.
features
Outstanding High temperature Performance
The tungsten-rhenium wire has superior strength as well as thermal stability due to its high melting and recrystallization temperature, which is unparalleled among wires. When exposed to high temperatures, it maintains structural integrity, and exhibits greater strength as well as lower creep compared to pure tungsten.
Good Ductility
Tungsten-rhenium wire is renowned for its superior flexibility, which can be attributed to its unique composition. The ductility of the tungsten-rhenium alloy wire improves significantly after rhenium is added to it. The wire is even more compliant, and can be shaped more easily after it has gone through recrystallization.
Excellent Electrical Properties
Owing to its greater resistivity unlike pure tungsten, tungsten-rhenium wire is able to sustain high levels of current without overheating. Its excellent conductivity also makes it applicable in situations with high-current densities.
Outstanding Thermoelectric Properties
Due to the high value of thermoelectric output from tungsten-rhenium wires, they are preferred high precision thermocouples for measuring temperature in high-precision thermocouples.
applications
Aerospace Applications
Satellite thruster nozzles and rocket engine parts are made with tungsten-rhenium wire due to the high temperatures they are exposed to. Tungsten-rhenium wire also has applications in aerospace high-temperature components and temperature measurement systems.
Electronics Industry
The wire serves in vacuum tube grids and heaters, and functions as an electrode in processes like electron beam welding and evaporation, thus expanding its range of applications in electronic components.
High-Temperature Furnaces
Tungsten-rhenium wire can withstand extreme temperatures while maintaining stable heating performance, making it suitable for use as a heating element in high-temperature furnaces.
Thermocouple Production
Tungsten-rhenium wire thermocouples have their applications in metallurgy, the chemical industry, and the power industry for measuring temperatures, making the wire ideal for producing high-temperature thermocouples.
Welding Industry
The heat and stress experienced during the welding process can be withstood by tungsten-rhenium wire, as it is used in making friction stir welding tools and has high strength and hardness.
