Tungsteno, or tungsten, is a chemical element with the symbol W and atomic number 74. It is known for its high density and exceptional hardness, making it one of the toughest metals. Tungsteno has a melting point of 3,422 °C (6,192 °F), the highest of all metals, which makes it valuable in applications that require materials to withstand extreme temperatures. This metal is commonly used in various industries, including electronics, lighting, and aerospace. In light bulbs, tungsteno filaments produce light when heated. Additionally, it is used in the production of cutting tools and armor-piercing ammunition due to its strength and durability.
