Tungsten wire can indeed be used to make high-temperature heating elements, mainly due to several key characteristics of tungsten wire:
High melting point: The melting point of tungsten wire is as high as 3410℃, which is the highest melting point of all metals. This feature enables tungsten wire to maintain stability at extremely high temperatures and is not easy to melt or deform, so it is very suitable as a material for high-temperature heating elements.
Excellent heat resistance: Tungsten wire not only has a high melting point, but also has excellent high-temperature stability, and can work stably for a long time in a high-temperature environment without failure. This makes tungsten wire an ideal choice for manufacturing high-temperature heating elements.
Good corrosion resistance: Tungsten wire exhibits good corrosion resistance in corrosive environments such as acids and alkalis, and is not easily corroded. This feature further enhances the reliability and durability of tungsten wire as a high-temperature heating element.
High strength: The tensile strength and hardness of tungsten wire are very high, which enables it to meet high-strength requirements when making heating elements and is not prone to breakage or damage.
Based on the above characteristics, tungsten wire is widely used in various occasions requiring high-temperature heating, such as halogen lamps, heating elements such as cathodes, anodes, and grids in electronic devices, and heating wires in thermocouples. These applications fully demonstrate the superiority and reliability of tungsten wire as a high-temperature heating element material.
