Vacuum coating industry

Vacuum coating industry


Tungsten is commonly used in the manufacturing of hot cathodes (or hot wires) for coated electron guns. Tungsten has a high melting point, good thermal conductivity, and mechanical strength, making it suitable for working under high temperature conditions and capable of producing stable electron emission. Tungsten molybdenum alloys are commonly used to manufacture other components of electronic guns. Tungsten molybdenum alloy is suitable for manufacturing various components in vacuum coating environments.
