Molybdenum Wire for Magnetron
Molybdenum wire for magnetron is a high-performance wire product specifically developed for the cathode structures of microwave magnetrons. It serves as a critical component in magnetron devices, typically used as the cathode filament or support element. With excellent mechanical strength, stable electron emission, and high resistance to oxidation and corrosion under high-temperature vacuum conditions, it is widely applied in household microwave ovens, industrial microwave heating equipment, and high-frequency electronics such as radar and communication systems.
Key Features
Outstanding High-Temperature Stability
Maintains excellent creep resistance and thermal stability at operating temperatures around 1400–1600?°C, with minimal risk of deformation, breakage, or grain coarsening.
Stable Electron Emission Performance
Low work function allows for consistent thermionic emission, meeting the stringent requirements of long-term magnetron cathode operation.
Superior Vacuum Compatibility
Resists sublimation and outgassing in high vacuum, ensuring internal vacuum environment stability and enhancing device life and reliability.
Excellent Precision Processability
Capable of being cold drawn to tight diameter tolerances, supporting precise dimensional and structural control of magnetron filaments.
Good Weldability and Material Compatibility
Exhibits strong metallurgical bonding with other electrode materials such as tungsten, titanium, and stainless steel, allowing for precise welding, brazing, or vacuum sealing.
