Tungsten is known for its high corrosion resistance, particularly to acids and alkalis. Compared to other metals commonly used for needles, such as stainless steel, tungsten is generally more resistant to corrosion. This makes tungsten needles a good choice for use in harsh environments or with corrosive materials. However, like any material, tungsten can corrode under extreme conditions, such as exposure to concentrated acids or bases at high temperatures. In general, the corrosion resistance of tungsten needles can be further improved by appropriate surface coatings or treatments.
