How Difficult Is It to Process Tungsten Wire?

The processing of tungsten wire is relatively difficult, mainly because tungsten has some special physical and chemical properties. The following are some of the main factors that make tungsten wire processing difficult:

High melting point: Tungsten has a very high melting point, approximately 3422 degrees Celsius (6192 degrees Fahrenheit). This means that processing tungsten at high temperatures requires special melting and processing equipment.

Hardness: Tungsten is a very hard material, harder than most metals. This means that harder tools need to be used when cutting or shaping, which makes machining more difficult.

Brittleness: Tungsten is relatively brittle at room temperature and easy to break. This needs to be handled with care to avoid cracks or breaks during processing.

Thermal conductivity: Tungsten has relatively poor thermal conductivity, so it may cause uneven heat distribution when processed at high temperatures, requiring special processing methods to control temperature.

Chemical stability: Tungsten has good chemical stability, but under certain conditions, such as in an oxygen atmosphere, tungsten oxide will be formed. This requires special handling to avoid oxidation.
