Introduction to the conductivity and chemical stability of tungsten wire
Good conductivity: Tungsten has good conductivity and relatively low resistivity. This allows the current to pass smoothly through the tungsten wire, generate heat and emit visible light. Although its conductivity is not as good as that of metals such as copper and silver, its conductivity is relatively stable in high temperature environments and can meet the needs of light bulbs.
Good chemical stability: At room temperature and general operating temperature, the chemical properties of tungsten wire are stable and it is not easy to react with oxygen, nitrogen, etc. in the air. This allows the tungsten wire to maintain its physical and chemical properties for a long time in the bulb, extending the service life of the bulb.
