Thoriated Tungsten Alloy Foil (W98/Th2)

Thoriated Tungsten Alloy Foil (W98/Th2) combines tungsten’s extreme melting point, high strength, and wear resistance with thorium’s ability to enhance electron emission and improve work function stability. In thin foil form, it is ideal for applications requiring precision, flexibility, and thermal endurance, such as high-temperature shielding, thermionic emitters, and components in vacuum electronics. Industries use this alloy foil for cathodes in electron tubes, high-intensity lighting electrodes, and aerospace thermal barriers. In research, it serves in advanced thermionic conversion studies, high-vacuum surface science experiments, and emission stability testing. The addition of thorium improves electron emission efficiency, while the foil geometry offers adaptability for custom high-performance components in both industrial and experimental contexts.
