Tungsten is known for its high resistance to corrosion, as it is a chemically inert metal that is not easily affected by most chemical environments. Tungsten needles, therefore, have excellent corrosion resistance and are used in applications where exposure to corrosive environments is a concern.
Tungsten needles are commonly used in the semiconductor industry, where they are exposed to harsh chemical environments during the production process. They are also used in medical applications, where they must be able to withstand exposure to bodily fluids and other corrosive agents.
However, while tungsten is highly resistant to most chemical environments, it can be corroded by some strong acids and alkalis, such as hydrofluoric acid and potassium hydroxide. In addition, tungsten can be affected by galvanic corrosion when in contact with other metals in the presence of an electrolyte. Proper handling and storage of tungsten needles can help prevent corrosion and prolong their lifespan.
