Thoriated Tungsten Alloy Spooled Wire (W99.4/Th0.6)

Thoriated Tungsten Alloy Spooled Wire (W 99.4/Th 0.6) is designed for high-temperature, vacuum-based applications requiring stable electron emission and structural durability. With 0.6% thorium oxide, it offers improved thermionic emission, reduced work function, and reliable arc initiation. This alloy is used in electron microscopes, ion sources, vacuum tubes, and plasma discharge systems. Its resistance to recrystallization and mechanical degradation at elevated temperatures makes it suitable for welding electrodes, fusion device components, and automated R&D setups. Supplied in spooled form, it allows precise integration into laboratory-scale assemblies and thermal systems, supporting materials science, aerospace simulation, and energy research.
