When tungsten is combined with other metals, we get alloys, highly resistant, heat controlling metals which can be utilized for different purposes. Tungsten is the 4th hardest metal on earth, and it gives stable and vigorous structure to other metals. Alloys have found wide application in many industries, especially because tungsten has the highest melting point and it is resistant to corrosion and acids. Tungsten alloys are mostly used for the following purposes.
Tungsten alloy fishing
They are used as weights to lure or bait and to increase the sinking rate, especially if you are casting from a distance. Depending on your use, they vary in size and shape. In the recent years, they are becoming popular because of the small size and the high density, which allows them to sing fast. They are slowly replacing the lead weights. The interesting thing about heavy tungsten alloys is that they concentrate the weight in the smallest possible space. They are often used for balancing.
Tungsten alloys for medical shielding
Due to their hardness, they are ideal for x rays and gamma rays. The high density of tungsten makes hard for radiation to penetrate and at the same time, it
protects the patients from dangerous radiation. Tungsten alloys are often installed in medical equipment and act as nuclear shielding. For example, PET scans are one of the nuclear medical tools available for diagnosis. Before the doctors proceed with an examination, patients are injected with a glucose-based radionuclide from shielding syringe made of tungsten alloy.
Tungsten copper alloy
When tungsten is mixed with copper, you will get a tungsten copper alloy. The amount of copper may vary, from 10% to 50%. This alloy has an excellent electrical and thermal conductivity, and it resists high temperatures very well. Tungsten copper alloys have a broad application, for example in aero industry, rocket nozzles are made from this mixture, as well as in electro industry.
