Formula: W 97/Re 3
Form: Wire
Material: Tungsten/Rhenium
Commodity: Alloys
Thermocouple Wire:
May Be Used As One Component Of A Thermocouple
Tungsten Rhenium Alloy Spooled Wire (W97/Re3) contains 97% tungsten for outstanding wear resistance and thermal stability, with 3% rhenium to reduce brittleness and enhance ductility in wire form. Supplied as spooled wire, it provides long continuous lengths for precision manufacturing and research use. Industries including aerospace, high-power electronics, and defense employ W97/Re3 wire in heating elements, thermionic emitters, and thermocouple assemblies. Specific applications include high-temperature vacuum furnace heating coils, aerospace monitoring sensors, and electron beam filaments. In research, W97/Re3 spooled wire is studied for creep resistance, microstructural stability under cyclic loading, and thermoelectric efficiency. The small rhenium addition gives enhanced flexibility without sacrificing tungsten’s high melting point or density, making W97/Re3 a critical wire alloy in aerospace, scientific instrumentation, and next-generation electronic systems.
