Rhenium Tungsten Cables

Extreme-Temperature Performance, Engineered for Precision

DOMADIA™ Rhenium Tungsten Cables are specifically developed to operate in ultra-high temperature and high-stress environments where conventional materials simply cannot perform. Blended from high-purity Tungsten and Rhenium alloys, these cables offer exceptional thermal stability, mechanical durability, and resistance to oxidation making them ideal for aerospace, nuclear, metallurgical, and scientific applications.

Product Overview

DOMADIA™ Rhenium Tungsten cables are typically made from W-3%Re or W-25%Re alloy combinations, which deliver unmatched performance at temperatures exceeding 2000°C. These cables maintain mechanical integrity and precision under extreme thermal cycling, vacuum conditions, and high-radiation exposure. They’re widely used in Type C thermocouples (W5Re–W26Re) and other advanced sensing and power transmission applications.

Types of Rhenium-Tungsten Thermocouples:

Precision-Matched Alloys for Specific High-Temperature Applications

DOMADIA™ offers a range of Rhenium Tungsten (Re-W) cable types, each tailored for specific applications where extreme temperature stability, strength, and thermoelectric performance are critical. The two primary alloy combinations -W-3%Re and W-25%Re -serve as the foundation for multiple high-performance solutions.

W-3% Rhenium / 97% Tungsten (W-3Re)

This low-Rhenium alloy offers increased ductility over pure tungsten and is widely used for structural wire, filaments, and furnace components. It provides enhanced workability and slightly reduced brittleness, making it ideal for high-strength, long-duration applications in controlled environments like aerospace or scientific equipment.

W-25% Rhenium / 75% Tungsten (W-25Re)

With significantly higher Rhenium content, this alloy offers superior thermal strength, conductivity, and creep resistance. It is commonly used in thermoelectric applications such as Type C thermocouples and in high-temperature vacuum systems, where consistent and accurate output under extreme heat is essential.

Type C Thermocouple Wire (W-5Re / W-26Re)

This combination features W-5%Re as the positive leg and W-26%Re as the negative leg. It is one of the most commonly used high-temperature thermocouple wire types, capable of operating reliably up to 2300°C. DOMADIA™ Type C thermocouple cables are used in metallurgy, aerospace testing, and nuclear environments for critical temperature measurement.

Stranded vs. Solid Core Configurations

DOMADIA™ Rhenium Tungsten cables are available in both solid-core (for stability and rigidity) and stranded configurations (for enhanced flexibility). This allows engineers to choose the ideal mechanical profile depending on the application and installation method.

Shielded and Jacketed Variants

For applications requiring signal stability or environmental shielding, DOMADIA™ offers cables with additional layers such as ceramic, quartz, or metal braid jacketing. These variants help improve durability and reduce signal interference in sensitive measurements or high-vibration environments.
