Tungsten is commonly used in the manufacture of coated electron gun hot cathode (or called hot wire). Tungsten has a high melting point, good thermal conductivity and mechanical strength, is suitable for working under high temperature conditions, and can produce stable electron emission.
Tungsten-molybdenum alloys are often used to make other parts of electron guns, such as crucibles, heat shields, etc. Tungsten-molybdenum alloy has good high temperature resistance, corrosion resistance and mechanical strength, and is suitable for manufacturing various parts in vacuum coating environment.
