High-purity 99.95% Pure W, Potassium-Doped Non-Sag (AKS), & W-3%Re Ductile Grade pure & Potassium-Doped Non-Sag tungsten (w / AKS) wire & heater coils (W / AKS-Doped W / W3Re, 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 & Potassium-Doped Non-Sag tungsten (w / AKS) wire & heater coils (W / AKS-Doped W / W3Re, CAS 7440-33-7) products deliver reliable performance in vacuum, inert-gas, and reducing furnace atmospheres.
Drawn with interlocking potassium-doped (AKS) grain boundaries or 3% rhenium alloyed for post-recrystallization ductility, our tungsten wires resist sag at incandescent temperatures above 2,200 °C. 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.
