Physical and chemical properties and preparation process of tungsten wire
To manufacture tungsten wire, tungsten powder needs to be sintered into a blank at high temperature, and then the blank is gradually stretched into a filament through processing processes such as drawing or extrusion.
Tungsten wire has a high melting point and melting temperature, which enables it to run for a long time in a high temperature environment without melting and breaking easily, so it is very suitable as a light-emitting element in a light bulb.
Tungsten wire also has good electrical conductivity and stable chemical properties. Its high conductivity allows current to pass smoothly through the tungsten wire without generating excessive heat and energy loss.
In addition, tungsten wire has high chemical stability at room temperature and is not easily corroded by common substances such as oxygen, moisture, acid and alkali, which can ensure the life and stable performance of the light bulb.
