Tungsten Rhenium

Tungsten-rhenium alloy is a solid-solution-strengthened alloy composed of tungsten as the matrix and rhenium. The rhenium contents commonly used in these alloys are 3, 5, 10, 25, and 26. It is divided into low-content W-Re alloys (Re ≤ 5%) and high-content W-Re alloys (Re ≥ 15%).
The tungsten-rhenium alloy has better mechanical properties and higher ductility than pure tungsten, and has high resistivity, which gives it better processability and weldability.
The tungsten-rhenium alloy possesses a range of excellent properties, such as a high melting point, high strength, high hardness, high plasticity, a high recrystallization temperature, high resistivity, a high thermoelectric potential, low vapor pressure, low electron work function, and low ductility and brittle transition temperature. Tungsten-rhenium is available in the form of wire, rod, plate, and sheet. Wire materials account for the vast majority and are primarily used as high-temperature structural materials.

The tungsten-rhenium alloy is a composite of two transition metals: tungsten (W) and rhenium (Re). This combination creates a material with unique properties, used in demanding environments. Here is a typical chemical composition for this alloy:

• Tungsten (W): Approximately 95% to 99% by weight
• Rhenium (Re): Approximately 1% to 5% by weight
