Tungsten is used in a variety of industries, including aerospace, heat treatment, oil and gas, and even medicine. Its high density and mechanical strength are extremely beneficial in all of the industries listed above.
Due to the extremely high density of tungsten, fasteners are frequently used in the balancing of rotating parts such as propellers.
Tungsten fasteners have a high mass due to the base metal, allowing them to block radiation and show up well on x-rays.
The metal is highly corrosion resistant and has a melting point of 3420 degrees Celsius, making it ideal for use in some of the most extreme vacuum furnace environments.
