1. Performance comparison of pure tungsten wire and tungsten rhenium wire
Pure tungsten wire: Once the tungsten wire is used for high temperature and recrystallizes, it becomes very brittle and easily breaks under impact or vibration.
Tungsten rhenium wire: It can reduce the brittle transition temperature of tungsten to room temperature or below. Used in some electric light source products that require high reliability, it can prevent the filament from breaking.
2. Comparison of usage of pure tungsten wire and tungsten rhenium wire
Purpose of pure tungsten wire: used to make filaments of various incandescent lamps and tungsten halogen lamps and electrodes of gas discharge lamps.
Uses of tungsten rhenium wire:
Production of tungsten filaments and chromatographic heat sensitive components with special requirements.
Used to make heating screen for TV heating and picture tube and camera tube.
Used in military electronic equipment.
