Incandescent lamps are traditional lighting devices that produce light by heating the filament to a high temperature. Tungsten wires, due to their unique physical and chemical properties, are the preferred material for incandescent lamp filaments.

Tungsten wire, as a high-temperature heating material, is often used as a heating element in ceramic sintering due to its high melting point, excellent electrical conductivity, and high-temperature resistance.

The durability of tungsten wire in high-temperature furnaces depends primarily on its material properties, environmental conditions, and usage.

Tungsten wire is widely used in vacuum melting furnaces, induction furnaces, electron beam melting furnaces, and other equipment, particularly in smelting processes requiring high-purity metals or special alloys in industries such as aerospace, nuclear, and electronics.
