Tungsten-Rhenium Thermocouple Wire

• Tungsten 5% Rhenium versus Tungsten 26% Rhenium wire
• Tungsten 3% Rhenium versus Tungsten 25% Rhenium wire
• Pure Tungsten versus Tungsten 25% Rhenium wire 

Concept Alloys takes care every step of the way to produce the finest quality tungsten-rhenium thermocouple wire, and provide the best customer experience possible. Our experts can help guide you to make the best material selection by discussing your application and providing supporting technical information.

We understand that thermocouple wire accuracy and uniformity are important and we go to extremes to achieve it. Special, proprietary processes are employed for this purpose. Uniformity is routinely measured by calibrating each end of every coil produced. We go even further by requiring that every finished coil meet our own end-to-end uniformity tolerance. All of these tests are performed over the entire specified temperature range – usually 200°F to 4200°F (100 °C to 2300 °C) depending on wire size - without extrapolation from lower temperature tests.

The diameter and roundness of all tungsten-rhenium wire is continuously measured using laser micrometer technology. This type of testing ensures that every coil of wire meets our rigid standards for dimensional uniformity. 

Tolerances refer to deviations from the °F nominal temperature – emf relationships defined by ASTM E230 and E1751.The accuracy guarantee represents the initial calibration tolerance of bare wire only. Factors that may affect accuracy in use include purity or quality of atmosphere or vacuum, wire size, temperature gradient, thermocouple geometry and insulation type and purity.

Experienced Staff - Our team has extensive experience in tungsten rhenium alloys, which allows us to provide unparalleled technical support and customer service.

Complete Alloy Availability - W/W26%Re, W3%Re/W25%Re, and W5%Re/W26%Re.

Doped 3% and 5% Alloys - Concept Alloys' doped 3% and 5% materials provide superior ductility to competitive un-doped materials.  

Calibration from 200 to 4,200 °F - Concept Alloys' innovative calibration system allows us to test materials to 4,200 °F or higher. Other manufactures simply extrapolate to these temperatures.

Certified to NIST-traceable standards, deviations in mV, and either °F, or °C - User-friendly certifications express deviations in both millivolts and °F or °C.

Special EMF Tolerances and Sizes Available - Special, tight tolerance wire is available for critical applications. We are fully capable of routinely providing any size wire from 0.0005 to 0.020 inch diameter. Larger diameters are available as special orders.

End-to-End Calibrations - Some customers prefer to use calibration data from both ends of long-length spools, rather than an average. This is available for a nominal fee.

Volume Pricing - Discounts from list price are available, and are based on annual usage rather than single buys.

No Minimum Order - Our goal is to meet your exact needs. No more, no less.

Most Orders shipped same or next day - Stock is maintained to support your just-in-time requirements. Our production and shipping systems allow for quick fulfillment of your rush orders. Stock sizes are .0005, .0008, 0.003, 0.005, 0.010, 0.015, 0.020, .032and .040 inch diameter.
