Metal tungsten pins are slender and sharp metal needles made of tungsten metal. It has the characteristics of high melting point and high hardness, and can be used in high temperature, high pressure, and high wear-resistant environments. Metal tungsten pins are mainly used in a variety of industrial and laboratory applications, such as engraving metal surfaces, cutting particles in collodion and manipulating single particles. However, because tungsten pins are so brittle, they may bend or break frequently.
Tungsten is itself a metal. Tungsten is a chemical element with an atomic number of 74. It is a transition metal and usually exists in the form of pure metal or alloy.
Broadly speaking, any needle-shaped object with tungsten as the main component can be called a “metal tungsten pin”. This may include pins made of pure tungsten, needles made of a tungsten alloy, or other alloys containing the element tungsten.
In specific applications, tungsten pins may be pure tungsten products, or they may be alloys containing other metal elements. For example, tungsten-cobalt alloy is a common cemented carbide in which the combination of tungsten and cobalt gives the material high hardness and wear resistance, so it may be used to make cutting tools.
