Not many materials in the world can sustain extreme pressures and scorching temperatures like tungsten can, and those are just some of the reasons why tungsten alloys are extremely popular in the modern-day industrial production. What this means is that all sorts of sectors are relying on this metal to provide them with tools and products, and a broad range of advantages come out of the usage of these superalloys. If you continue reading this in-depth guide, you will have an opportunity to learn more about this highly interesting and unique metal. Tungsten bar is crafted in a furnace using four tungsten ore, to make it extra hard and resilient.
Basic Facts About Tungsten
Element 74 in the periodic table is also known as Wolfram, and the term tungsten is derived from the Swedish language. Their words “tung sten” literally mean “heavy stone”, and this use of term clearly illustrates the essential features of this metal. In other words, tungsten is twice as heavy as lead, and it also has very high density – double the density of steel, for example. Durability and strength of this metal are also “legendary,” which means that even a small volume of tungsten alloy can create products with impressive characteristics. Superior wearing resistance and high tensile strength of this metal can also play a significant role in the metal fabrication, and on top of all that – tungsten alloys can easily resist corrosion and they have good resistance to impacts.
Other Characteristics Of Tungsten Alloys
Since tungsten in its pure form is highly expensive and even brittle, it is combined with other elements to create high-performance alloys. For instance, these two-phase composites usually come in the form of W-Ni-Fe or W-Ni-Cu formula, and they are generally refractory metals. The percentage of actual tungsten in these composites can vary depending on the purpose of the material, but some alloys can contain up to 97% of Element 74. These superalloys and high-speed steels are extremely versatile when it comes to their usage, and this is the also reason why China is earning impressive amounts on the export of this particular commodity.
The Usage Of Tungsten Alloys
Ever since the early days of incandescent light bulbs, which were the most popular products made with tungsten filaments, tungsten has gradually been spreading into different areas of industrial production. Nowadays, machining and TIG welding are not the only sectors where tungsten alloys play a significant role.
For example, sports and leisure also need tungsten in relatively small quantities, for creating darts, golf clubs, and similar objects and equipment. Similarly, the automotive and aerospace industry rely on the durability and high density of tungsten alloys, in combination with its ability to sustain extremely high temperatures without melting. In recent years, the military has been conducting extensive testing on the use of tungsten in the production of bullets and other projectiles, and medical diagnostic equipment also can require certain quantities of this metal. X-rays and radiation devices need tungsten as a shielding mechanism, and its high density is the perfect characteristic when it comes to this purpose.
