Tungsten is a rare and valuable metal that is widely used in a variety of industrial applications. It is known for its high melting point, which makes it an ideal material for use in high-temperature applications such as electrical wires, heating elements, and filament wires for incandescent light bulbs. Additionally, tungsten is often used as an alloying agent for other metals, which can improve their strength and durability. Tungsten is also used in the production of armor-piercing ammunition, as well as in the construction of nuclear reactors due to its ability to absorb radiation. However, the mining and processing of tungsten can have adverse environmental impacts, so there are ongoing efforts to find more sustainable and environmentally friendly sources of this important metal.
