Although high-efficiency lighting technologies such as LEDs are gradually replacing traditional incandescent lamps, tungsten wire still holds irreplaceable advantages in high-temperature lighting systems due to its superior physical and chemical properties, particularly in incandescent lamps and certain specialty lighting equipment. 1. Properties of Tungsten wire Tungsten has an extremely high melting point (approximately 3422°C), one of the highest melting points of naturally occurring metals. This allows it to maintain structural stability at high temperatures. Furthermore, tungsten has moderate resistivity, a…
