Tungsten is a chemical element with the symbol W and atomic number 74. It is known for its remarkable hardness and high melting point, making it one of the toughest metals. Tungsten is often used in applications that require durability, such as in light bulb filaments, cutting tools, and military projectiles. This metal is found naturally in minerals like wolframite and scheelite. Due to its density, tungsten is also used in the production of heavy alloys and counterweights. Its unique properties make it valuable in various industries, including aerospace, electronics, and manufacturing.
