High-purity 99.95% Pure W & Non-Radioactive Lanthanated (1.5–2% La2O3) / Ceriated (2% CeO2) pure & doped tungsten (w, WL15, WL20, WC20) rods & electrodes (W / W-La2O3 / W-CeO2 / W-Y2O3, CAS 7440-33-7) 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 pure & doped tungsten (w, WL15, WL20, WC20) rods & electrodes (W / W-La2O3 / W-CeO2 / W-Y2O3, CAS 7440-33-7) products deliver reliable performance in vacuum, inert-gas, and reducing furnace atmospheres.
Swaged and centerless-ground tungsten rods and non-radioactive rare-earth-oxide doped electrodes (WL15, WL20, WC20) provide low work function (~2.7–3.0 eV), superior arc ignition, and high creep resistance. 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.
