What is Potassium-doped Tungsten Wire?

Potassium-doped tungsten wire is a specially designed tungsten wire. Its main function is to maintain a stable shape under high temperature conditions and prevent the tungsten wire from sagging or deforming due to high-temperature thermal expansion. This type of tungsten wire is commonly used in high-temperature furnaces, vacuum furnaces, electric arc furnaces, high-temperature heaters, electronic device manufacturing, and other applications that require working in extremely high-temperature environments.

Potassium-doped tungsten wire is usually made of pure tungsten or tungsten alloy and has the following characteristics:

High melting point: Tungsten has a very high melting point, about 3422 degrees Celsius (6192 degrees Fahrenheit), which makes it less likely to melt or vaporize at high temperatures.

Low coefficient of thermal expansion: Tungsten has a low coefficient of thermal expansion, which means that at high temperatures, its linear expansion is relatively small, helping to maintain a stable shape.

High strength: Tungsten has good mechanical strength and can resist the influence of gravity at high temperatures and prevent sagging.

Corrosion Resistance: Tungsten has high corrosion resistance to most chemicals, making it suitable for use in a variety of industrial environments.

Conductivity: Tungsten is a good conductive material and is suitable for applications that require both conductivity and high temperature stability.
