Tungsten needles are usually made of tungsten or tungsten alloy. Tungsten is a chemical element with an atomic number of 74, a high melting point and hardness. Due to its unique properties, especially its high melting point and high hardness, tungsten is an ideal material for applications requiring high temperatures, strength and hardness.
In some cases, tungsten alloys are also used in the manufacture of tungsten needles to improve specific properties. A common tungsten alloy is tungsten-cobalt alloy, where cobalt is used to improve the toughness and processability of the alloy. This alloy is commonly used in applications such as manufacturing carbide cutting tools and has good cutting properties.
Generally speaking, due to the excellent properties of tungsten, tungsten needles made of tungsten or tungsten alloy are widely used in situations with high temperature, high hardness and high strength requirements, covering many fields, such as EDM, medical, and cutting tools Manufacturing etc.
