High Melting Point Diameter 0.265mm Tungsten Filament For Photoelectric Industry

High Melting Point 3420 ℃ Diameter 0.265mm Tungsten Filament For Photoelectric Industry

1. Introduction Of Diameter 0.265mm Tungsten Filament For Photoelectric Industry:

Due to the high melting point, high hardness and non-corrosion characteristics of tungsten, photoelectric tungsten wire is mainly used in optical communication, laser, photoelectric display, optics, solar photovoltaic, electronic engineering, logistics network and other fields. Several wire drawing dies are typically used to draw tungsten wire. The main purpose is to manufacture filaments and high-speed cutting alloy steel, and also used in optical instruments, chemical instruments, etc.

3.Characteristic Of Diameter 0.265mm Tungsten Filament For Photoelectric Industry:

High melting point,

High resistivity,

Good strength,

Low vapor pressure

The resistivity of tungsten wire is 5.3*10^-8. High resistivity, high melting point, strong strength, and low vapor pressure are all characteristics of tungsten. Among all the pure metals, it is the one that produces incandescent filaments the best. Yet, processing tungsten is challenging because to its hardness and fragility. When the current passes through the tungsten wire and is heated to a certain temperature, the resistance value of the tungsten wire increases to a certain value (the resistance value of the general metal wire increases with the increase of temperature).
