What Is the Oxidation Resistance of Tungsten Wire?

Tungsten wire has excellent antioxidant properties, which is one of the important reasons for its wide application in high temperature environments. Here is some key information about the oxidation resistance of tungsten wire:

High melting point: Tungsten has a very high melting point, approximately 3,422 degrees Celsius (6,192 degrees Fahrenheit), which allows it to maintain its physical and chemical stability in high-temperature environments. This means that tungsten wire can withstand high-temperature refining, heating and high-temperature furnace applications.

Anti-oxidation film: At high temperatures, a strong oxide film called tungsten oxide will form on the surface of tungsten wire. This oxide film prevents further oxidation of tungsten and protects the underlying structure from oxidation. This oxide film is stable and helps maintain the performance of the tungsten wire.

Chemical stability: Tungsten has good resistance to most chemicals and is not easily attacked by acids, alkalis or other common chemicals. This enables tungsten wire to be widely used in the chemical industry.

Vacuum applications: Due to its high oxidation resistance and chemical stability, tungsten wire is often used in vacuum equipment and electronic devices, especially in high vacuum or ultra-high vacuum environments, to maintain its performance.

Arc Welding: Tungsten wire is also used in arc welding because it remains stable under the high temperature conditions of the welding arc and is not easily melted or damaged.
