High-purity Matched EMF Calibration Grade (ASTM E988 / IEC 60584 Type C & Type D) Tungsten-Rhenium thermocouple wire (type c, type d & type g) & probes (W5Re / W26Re & W3Re / W25Re, CAS 7440-15-5) engineered for ultra-high-temperature vacuum furnaces, crystal growth, semiconductor processing, and corrosive environments.
Consolidated by powder metallurgy, vacuum arc remelting (VAR), or electron-beam melting and stress-relieved for high-temperature dimensional stability, our Tungsten-Rhenium thermocouple wire (type c, type d & type g) & probes (W5Re / W26Re & W3Re / W25Re, CAS 7440-15-5) products deliver reliable performance in vacuum, inert-gas, and reducing furnace atmospheres.
Above 1,700 °C where Platinum-Rhodium (Type B/R/S) thermocouples soften or melt, matched Tungsten-Rhenium Type C (W5%Re vs. W26%Re) and Type D (W3%Re vs. W25%Re) wires measure vacuum and inert-gas furnace temperatures continuously up to 2,315 °C (4,200 °F). Every shipment includes the producing mill's chemical purity Certificate of Analysis (reporting metallic and interstitial O, N, C, H trace levels in ppm) and pre-shipment dimensional verification.
