Tungsten, also known as wolfram, is a chemical element found in the Earth's crust and is identified by its atomic number 74. It belongs to group 6 of the periodic table and has an extremely high melting point (3422 degrees Celsius). Tungsten primarily comprises tungsten-99, which in turn comprises carbon-14 and oxygen-18 isotopes. It has a silvery metal look with excellent electrical conductivity. Its most common form is wolframite ore, ferberite ore and scheelite ore.
Tungsten is one of the densest elements on Earth, meaning it has a very high melting point (3422°C), which makes it an ideal material for different uses. It is highly corrosion-resistant, making it suitable for medical implants and components exposed to harsh environments. Additionally, its low level of thermal expansion allows tungsten to be used as a filament in light bulbs due to its stability when heated and its ability to maintain structure during cooling. Tungsten's tensile strength makes it appealing in the industry as the metal can withstand high pressures without deforming or breaking. Lastly, tungsten alloys, such as fishing lures, are often used as weights due to their heaviness compared with other metals of similar sizes.
