Product Description

Tungsten Rhenium Wire

What is tungsten rhenium wire?
Tungsten rhenium alloy wire doped with rhenium has much better ductility and stability than pure tungsten at high temperatures. The melting point of the tungsten rhenium alloy wire is 3120~3360. The tungsten rhenium alloy wire can be used to reach up to the peak of 3000, it can be used for making the most heat-resistant metal thermocouple. It has high EMF and high sensitivity. It can't be dissolved in any isolated acid.


Application
1. Production of specific lighting filaments, thermo-sensitive elements for chromatograph
2. For making heaters and grid wire for TV tubes and image-pick-up tube
3. For military electronic devices


Advantages
Rhenium significantly reduces the brittle characteristics of tungsten at room temperature. What is more, the addition of rhenium increases the recrystallization temperature, ductility, and the ultimate tensile strength of these alloys and decreases the ductile-brittle transition temperatures of tungsten-rhenium alloys.
