Tungsten Rhenium Thermocouple Wire is made from different compositions of W-Re alloys.
Tungsten rhenium alloy can be used over a wide temperature range (-196°C to 2,760°C) and standard temperature tables (ASTM E230 and E1751) are available from 0°C to 2315°C. Rhenium improves the properties of tungsten. Tungsten rhenium alloys are more ductile at low temperatures while stability under high temperatures is improved as while. The effect increases with the rhenium concentration and usually WRe alloys are produced up to 26% of Re. The cost of these materials is relatively lower compared to noble Pt and Rh.
W-Re Thermocouple Wire Description:
Tungsten Rhenium Alloy Wire
Edgetech Industries LLC is a global supplier of Tungsten Rhenium (W-Re) Alloy. Tungsten Rhenium alloy is an alloy of tungsten and rhenium.
Low rhenium alloy: containing rhenium 5% or less
High rhenium alloy: containing rhenium from 20% to 30%.
A pair of low rhenium alloy and high rhenium alloy can be used to measure the high temperature of 1500~3000 ℃ as thermocouple wire. The use of tungsten rhenium thermocouple wire instead of platinum and rhodium thermocouple wire can save costs.
The typical composition of W-Re Alloy Wire is WRe3, WRe5, WRe20, WRe25, WRe26 (Rhenium content: 3%, 5%, 20%, 25% and 26%).
